Hello i had sex on one of my fertile days which was January 15th I have been a little tired and have been going to the bathroom a lot during the day and off and on cramping the past couple of days. I took a HPT around January 25th because I wasnt feeling like myself. I was scheduled to come on my menstrual February 2nd. this morning I went to the bathroom and i had brown spots when i wiped its now 3pm and my period has not come down yet.... How long should i have the spotting for my period to come down?
