I had unprotected sex nearly 2 weeks ago during the time of the month that I am supposed to ovulate. 3 days later I had a brown mucusy discharge. It has continued in and off for nearly a week now. And it was as though I was having my period but very very light. My period due date is in a few days so I am waiting till then before I take a pregnancy test. Has anyone had an similar experience to this and/or have any advice?
