Hello there. I could use some educated advice.

I've been on the BC pill (Microgestin) since the 20th. I had taken the first 8 pills exactly on time, every morning. Had unprotected sex that night. Woke up in the morning, realized I didn't have the pills with me to take, and decided to have sex that morning anyway. Which seems like an idiot move, looking back. Anyway, I'm wondering if pregnancy is likely, considering we had sex a couple times when the pill was 3-4.5 hours late and this is within the first two weeks of me being on BC ever. If it matters, he did pull out the later time that morning. Also, I took the pill as soon as I returned home (~7 hours after time I usually take it) and again at the normal time the next morning.

I'm within 72 hours of having sex, so I could get the morning-after pill if need be. But I'm somewhat self-conscious about purchasing that, and would rather not if it's unnecessary.

Thanks in advance for any advice!
