My boyfriend and I had sex on the 7th and the condom broke. He didn't ejaculate and if he did it was only a small amount. My period was expected the 9th. It felt like I was going to start, I had normal cramps, just no bleeding. I took the plan B pill that evening around 9. I woke up at 4 am with sharp pain in my lower abdomen. This morning around 11 I noticed that I had slight discharge that was a brownish color. I still have this, very slight, all day. I'm not sure if this would be from my period trying to come and the plan B stopping it or if it could be implant bleeding. We have previously had sex but never had any issues with condoms but I know anything is possible. If anyone could help ease our minds that would be fantastic.
