“Women should be aware that if they have an irregular period, it can make the ovulation days difficult to determine.” Said Dr. Martinelli. “When examining fertility, it’s important to realize that an egg can survive for about 24 hours after ovulation, and sperm can live inside a woman’s body for three days—though sometimes it’s possible for them to survive for five days. “
How long should a normal menstrual cycle last?
An average menstrual cycle lasts 28 days, defined from the first day of menstrual bleeding to the first day of bleeding of the next period. However, irregular periods are very common. An irregular period is defined as a cycle that varies by more than seven to nine days.
There are several reasons why women may have abnormal periods, which can include fibroids, ovarian cysts, polyps, and even something as common as stress.
“If you’ve constantly had an irregular period, please contact us for an appointment to determine the underlying cause and initiate treatment,” said Dr. Martinelli.
When does ovulation start?
If you have a normal 28-day cycle, ovulation should occur about 14 days before you start your next period.
When can I become pregnant after my period?
If you have intercourse five days before ovulation until one day after ovulation, you can become pregnant. You’re much more likely to become pregnant if there are live sperm in the fallopian tubes during ovulation.
Fertility Awareness and Family Planning
Some women use fertility awareness as a method of natural birth control. One of the tools used is something called the Standard Days method. This establishes that if you have a period that is between 26 to 32 days long, days eight through 19 will be your most fertile days. However, this method is most effective when you have regular menstrual cycles.
If a woman has a regular period and uses the method perfectly, less than one to five women out of 100 will become pregnant. However, the key words here are “perfect use.” The typical use rate is different. Typical use means that the methods may be done incorrectly or measured inconsistently. In the first year of this typical use, 12 to 24 women out of 100 will become pregnant. (American College of Obstetricians and Gynecologists)

You might have heard that you can't get pregnant right after your period. But in reality, people sometimes can conceive by having penis-in-vagina (PIV) sex immediately following menstruation. Read on to learn what experts say about your chances of getting pregnant right after your period.
Your Menstrual Cycle and Conception
"There are two phases to the menstrual cycle: the follicular phase occurs before ovulation, and the luteal phase occurs after ovulation," says Lauren Sundheimer, M.D., MS, FACOG, an OB-GYN practicing in Orange County, California. Dr. Sundheimer explains that people who have 28-day cycles typically ovulate approximately 14 days after the first day of their period.
Though ovulation tends to occur 14 days prior to the next period, cycle length varies for from person to person and even cycle to cycle. This variation can make predicting ovulation especially tricky if you have irregular cycles since you don't know when your next period will arrive.
The egg that's released during ovulation survives for only 24 hours. Sperm, on the other hand, can survive three to five days in the uterus and fallopian tubes under the right circumstances, says Barbara Stegmann, M.D., a triple board-certified OB-GYN and women's health clinical lead at Organon, a global health care company. So having PIV sex during ovulation or the days beforehand can result in pregnancy since the egg can meet with existing sperm in the reproductive tract.
Your Chances of Getting Pregnant During Every Phase of Your Cycle
But "if the egg is not fertilized by a sperm during this time, it does not survive," says Michele Hakakha, M.D., a board-certified obstetrician and gynecologist based in Los Angeles and co-author of Expecting 411: Clear Answers and Smart Advice for Your Pregnancy. Then, about 12 to 16 days later, your uterine lining sheds, resulting in your period.
Can You Get Pregnant Right After Your Period?
For most people, pregnancy isn't likely to happen right after your period—but it is possible. As early as the third day of your menstrual cycle, your levels of the reproductive hormones progesterone and estrogen, which taper off at the start of your period, begin to climb and help your uterine lining rebuild.
Here are a few scenarios that can lead to conception immediately after menstruation.
You have a short menstrual cycle
Although an egg doesn't typically release during the immediate post-period phase, called pre-ovulation, your chances of conceiving aren't zero. Sperm can live up to five days in fertile cervical mucus. That means they can stick around for a few days until your body does release an egg during ovulation. If you have a short menstrual cycle, you may be fertile soon after your period ends.
For example, if you ovulate on day 11, it is technically possible to get pregnant from sex as early as day six of that cycle, which may be right after your period ended.
"One study showed that people who had sex only one time during this phase still got pregnant," says Steven R. Bayer, M.D., a Boston-based reproductive endocrinologist. In fact, a 2018 study in Obstetrics and Gynecology examined PIV intercourse patterns in people trying to conceive with the help of ovulation tests. Researchers found an increased pregnancy likelihood in the days leading up to ovulation—18.5% for day one and 23.6% for day two.
You miscounted cycle days
You can also get pregnant if you miscounted cycle days and mistakenly had unprotected PIV sex near ovulation. To determine day one of your menstrual cycle, start counting on the first day of red blood rather than at the end of your menstrual period, says Dr. Sundheimer.
"The duration of bleeding for a period also varies, so when you're counting time to ovulation, it's better to count from the first day of a period rather than days since bleeding stops." Doing so can prevent you from having sex too close to ovulation, which can lead to pregnancy.
Your period lasts a long time
It's not uncommon to have spotting in the day or so before your period starts and for a few days after that. Because of this bleeding, you might falsely believe you're still on your period and can't get pregnant. In reality, though, ovulation can be closer than you think.
Can You Get Pregnant On Your Period?
Managing Fertility After Your Period
You don't want to worry about getting pregnant before you're ready. That's why it's essential to know your cycle and your body and use protection whenever there's a chance you could get pregnant. Having a birth control plan (and possibly a backup plan) in place is especially important when you're actively trying to avoid pregnancy.
If you had unprotected PIV sex during your period and are concerned that you may be expecting, look out for early pregnancy symptoms like mild lower abdominal cramping, breast tenderness, and moodiness. Other common pregnancy symptoms will manifest closer to six or seven weeks of gestation, including nausea, vomiting, and fatigue.
