Is Plan b effective on the day of or after ovulation?

my boyfriend and I had unprotected sex when I was ovulating. He finished inside of me and I took a plan b pill two hours after. I actually have a few questions about plan b and possible pregnancy.

I’m about 260 pounds. When my boyfriend bought me the pill, the pharmacist mentioned the study claiming that this specific type of EC doesn’t work as well on Overweight women. I was wondering about that. Also, because took the pill when I was ovulating is there a chance pregnancy may still be a possibility?

Hello, ErikaLynn_96. Thank you for posting.

Your pharmacist was right to inform you about the study. Emergency contraceptives are up to 95% effective when taken as prescribed within the first 24 hours and up to 90% effective when taken within 72 hours. It works by preventing ovulation and stopping a pregnancy from starting. It will not end a pregnancy already in place. Side effects can include stomach aches, headaches, nausea and a general feeling of being unwell. The more frequently they are taken, the more likely a woman is to have side effects and an irregular cycle. They should be taken only for emergencies, not used as a method of birth control.

Symptoms usually start 2-7 days after taking the medication and may or may not include bleeding or spotting. If a woman doesn’t get her next period within a week of it’s expected a date, a pregnancy test is advised. Periods can often be delayed or longer/shorter as a result of taking ECP. They should get back to normal by the second cycle. Each woman is different and we cannot predict what each woman's experience will be with ECP.
