Hey, i had unprotected sex 2 months ago today, i had my period the first month and it was 36 days (about a week late) and mine are normally 30 days and have been for the last year, and this month i havent had my period yet and im at day 36 now, i havent been overly stressed or change anything in my diet etc.. i have taken two pregnancy tests and both are negative, so im just a bit curious to what is going on, also i have been getting a slight smelly discharge and cramps in the pelvic region, could i be pregnant?? or what could be causing this??
