I am now almost one week into my missed period, it was meant to be due on the 16/04, i had sex with my bf on the 7/04 and have had pink brownish very light spotting which lasted a few days. The past 2 days i have been having white milky vaginal discharge, im so worried. I've taken 2 pg tests, one done on the 18/04 during the day and was negative and the second one done today 21/4 with first morning urine and came negative. Im really stressed out and worried, WHAT IS GOING ON WITH MY BODY?? :'(
