"i had unprotected sex the day after my period on july 1st.  scared like crazy because i had a scare before that i made my boyfriend go to the store 12 hours later to get me plan b. (he didn&#039;t think i needed it but you never know ) i took it as soon as he bought it and had to wait a month for my next period. i kept thinking i was pregnant. but i got my period two days early and i&#039;m currently still on my period. it&#039;s very heavy with a lot of back pain but i&#039;m happy i got it. thank you plan b!!"
