I have been on BC for 5 months now and am a typical user (never missed a pill, but take them within the expected hour, no more than that). My partner and I don't use condoms. For the first time, he ejaculated in me and we were both afraid so I took the plan b pill (which i know is dangerous because of the amount of hormones) and continued to take my birth control regularly. 5 days later we had unprotected sex again but didn't take the plan b pill. Will the plan b pill compromise my birth control pills effectiveness? I'm afraid of the second act of unprotected sex and the possibility of pregnancy because of plan b.
