I started my new bc on the 2nd of this month. I took it for over two weeks before having unprotected sex, and he came in me. I took it religiously, every day at the same time, the entire pack.

The week before my period, I get cramps and spot a little. I did this this past week, but it was brown blood mixed with normal discharge. I am worried that it was implantation bleeding, as this would be two weeks from the day he came in me. I am a day late to my period, which could make sense as my last month cycle was a little messed up. I am not having cramps anymore, and I haven’t had any dark discharge/spotting like I normally do. I am terrified I might be pregnant.

Does this sound like implantation bleeding or just old blood ?
