I have PCOS. My periods are never regular. (The <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> said I should have started my period 2 days ago).Over the course of the last week i had a red dime size mucus that lasted 1 day. then it became a dark brown for about 2 days. and the last 3 days its been a super light brown color. Today ive been bloated and i have cramps. My husband doesnt believe im pregnant. What else could it be?
