After my period finished me and my boyfriend had sex the condom was broken but before he finished my boyfriend pulled out and 100% finished out side.But just to be sure i took the day after pill in the first hour this happened. After 2-3 days i got period like cramps and brown spotting when the spotting finished i felt pain in my breasts they hurt for 4 days and today they stopped and when i looked at them the nipple has gotten bigger and darker.Please help am i pregnant or is it hormones
