When it comes to concerns about contraceptive use after ovulation, it's essential to understand the timing of ovulation, the effectiveness of emergency contraception, and the proper usage of these medications.

Based on your menstrual cycle, with an expected ovulation date around March 29 and your last menstrual period starting on March 16, you are indeed in a window where ovulation could occur. Sperm can live inside the female reproductive tract for up to five days, so if you had unprotected intercourse on March 31, it is possible that sperm could still be viable if ovulation occurred shortly after.

Emergency contraception (EC), often referred to as the "morning-after pill," is designed to prevent pregnancy after unprotected sex or contraceptive failure. There are different types of emergency contraceptive pills, including those containing levonorgestrel (Plan B) and ulipristal acetate (Ella). The effectiveness of these pills is highest when taken as soon as possible after unprotected intercourse, ideally within 72 hours for levonorgestrel and up to 120 hours for ulipristal acetate.

Regarding your specific situation, you mentioned that you received a recommendation from a pharmacist to take three pills in one day. This instruction may vary depending on the type of emergency contraception you were given. For example, if you were prescribed a regimen of levonorgestrel, the standard dosage is typically one pill taken as soon as possible after unprotected intercourse, with a second pill taken 12 hours later (if applicable). If you were given ulipristal acetate, the recommendation is usually to take one pill as a single dose.

It’s crucial to follow the specific instructions provided with the medication you received. Taking more than the recommended dosage does not increase effectiveness and may lead to unnecessary side effects, such as nausea or fatigue.

In terms of your concerns about the effectiveness of the emergency contraception, it’s important to note that while these medications can significantly reduce the risk of pregnancy, they are not 100% effective. Factors such as timing of ovulation, how soon the pill is taken after intercourse, and individual variations in metabolism can all influence effectiveness.

If you continue to have concerns about potential pregnancy after taking emergency contraception, consider taking a pregnancy test about two weeks after the incident or consult with a healthcare provider for further guidance. They can provide personalized advice based on your health history and current situation.

In summary, if you had unprotected intercourse close to your ovulation date, taking emergency contraception as soon as possible is the right approach. Make sure to adhere to the specific instructions for the medication you received, and don’t hesitate to reach out to a healthcare professional for any lingering concerns or questions.
