I am in a relationship, and currently not on any form of oral or IUD BC (due to epilepsy medication) except for condom usage. On July 20th, the condom broke and my partner and I hadn't noticed until after sex so I took plan b 12 hours later. A week later I had bleeding for a week so I feel it has worked. Now yestersay evening, August 1st, my partner and I had sex and before we put the condom on we had sex with no condom for a few minutes (no ejaculation, pre-cm obviously) it was for feeling. My worry is, I was ovulating I think from my tracking and my cervical mucus. Should I take plan B again?!? Is there a chance pre-cm will impregnate me? There was no orgasm, only with the condom on did he orgasm.
