"took plan b a day after my boyfriend had finished inside me. i&#039;ve been on the bid control pill for a while but forgot to take 2 pills from the 1st week. side effects i got were stomach pain, nausea, and diarrhea. worst experience ever. will not take it again, rather find another way to not forget to miss my pill. after a week and half i got my period so it works but with bad side effects."
