i am having cramps and breast tenderness and was spotting yesterday, my period is due tomorrow but i had sex yesterday. in the middle of it, i had bleeding (like a lot) so i thought i had my period. but after sex i didnt bled anymore. now, i am no longer spotting but i am still having cramps. also, after sex, i had terrible cramps. is this normal? why did my bleeding stopped? when will i have my period?
