I've been on birthcontrol for about 2 months. My last pack, I forgot to take 2 pills and I took 3 in one day. Which I realized after was not what I should have done. anyway, so my period came 2 days early, starting on a Sunday. It ended on Friday and I kind of had old blood spotting for a few days. due to work issues, I didn't get my new pack of BC until today, which is a Monday. I took 2 pills since I wasn't able to take my pill yesterday as I should have. Today I had sex and my bf pulled out, but he got some on/possibly inside of me. should I take a plan B?
