The past two days when I have gone to the bathroom, when I wipe the toilet paper is brown accompanied by stretchy brown blood/discharge. I had my period two weeks ago. I don't start my fertile window for a few days, and I have a very long cycle (34-38 days) does anyone know what causes this or why it is happening? I don't believe I'm pregnant but did have unprotected sex on day 1/2 of my last period.
