Me and my boyfriend had unprotected sex on 12/24 he didn’t cum in me (yes I know about pre-cum). Then on 12/27 we had sex again and this time he came inside me. I couldn’t get a Plan B that day so I got one the next day. On 12/31 he came inside me once again and I never had an opportunity to get a plan b. When all of this happened, I was in my fertile window according to this app. I did notice some bleeding starting on 1/2 lasting til about 1/6. The bleeding on the first day was a bright red then it became brown. It wasn’t like my period or anything, I was thinking it was the Plan B messing up my cycle but I’m not for sure. I say all of that to ask if there’s a good chance I could be pregnant.
