Y'all I have no idea what the hell to do so last week we had sex 4 times in one day, three days later sex again, two days later then the next day and the next which was on the 11 was our last day and he had pulled out alittle too late . So here I am almost a week after all that and a week before my period start date having a lot of discharge( a watery milky type) I have not been itching except for my hair that is growing back which does sometimes cause it to itch but anywho it just dawn on me with my nips itching, being tired all the time even after a waking up, my mood swings please someone tell me if I am going crazy or if they had the similar thing
