Hi, i dont really know how to ask this w/o being awkward, but me and ky partner had unprotected sex, then a week before my period was due i had light bleeding (so it was heavier than spotting but not a period i think) and now on the day my period is due i did a test and it was negative - so i really dont think i am pregnant??? Also i dont have and sti/std's. Does anyone know what i might have/be???? Please help xx
