So i took the morning after pill about 4 days ago, and my breast have been really really sore today. I still haven't gotten my period either. I took the morning after pill because i was paranoid of getting pregnant (even though we used a condom) i took it 3 days after the first time and i had also had protected sex the day i took it. I know it was unlikely that i could've been pregnant but I was terrified. Anyway i had sex again 2 days after taking the pill (protected again) but yesterday and especially today my breasts have been really sore and I've felt kind of sick. I don't know if I am just being stupid and paranoid but i need some reassurance please.
