Whats the difference with implatiation cramps and pms period cramps.. okay so I just found out that I was ovulating on the 13 my bf & I had sex 11-15th (he finished inside me).. I saw women on here say implantation happens 7 dpo.. okay if that's the case yesterday was the 7th day I've been cramping a lot since like Thursday & it hurts & my boobs are extremely sore ,back killing me (basically period symptoms ) but crazy thing is my period is in 5 days so this also could be period cramps right?? I swear I hate being a women sometimes 😨😥😔😟
