Ok so I'm currently taking Microgestin Fe 1/20, and last month the day after my period ended I had unprotected sex, and my boyfriend came inside me. I take my pill around 8-8:30 pm every night, I take it late sometimes, but never after 11. I am currently on my 4th brown pill for this month, and I've been getting light brown bleeding instead of my period. My breasts weren't as sore, and I've been having cramps. I've been taking this pill since November of last year. Could I be pregnant? Sidenote: The first month I started taking them, I lost one of my brown pills, so I just take one from the next pack. Idk if that affects anything.
