I Had unprotected sex over a month ago, i had spotting that lasted a day, but over a week later i thought i got my period (So obviously i didn't take a test). and it lasted the usual amount of time, throughout my whole cycle i had white creamy CM.  3 days ago I Had unprotected sex again and the NEXT DAY. i started bleeding. it was pretty heavy yesterday but no thick clotting, today its lighter and still no clotting but some tiny clots, like a grain of sand to a sesame seed, nothing bigger. but currently i'm having SEVERE cramping that feels like i want to cry. im so confused as to whats going on!! Could this be pregnancy? Miscarriage? or just a bad period??
