i had unprotected sex and began to feel bloated for 3 days following that, then my period came and it lasted for 5 days,it was a normal flow and then it just completly stopped, it was there the morning of the 5th day and that same night it just went away without a trace, it did not get lighter is just cut off completley but now i have a slightly white watery discharge no itching or fould odor and i feel some pressure around my pelvis like i'm ovulating .what could this be?
