I've had my I.U.D in every since 2010. I've experienced things like not being able to keep up with my cycle sometimes, horrible pains in my stomach, brown fluid instead of red, late cycles, and missed cycle once. This month my period is late and two days ago I wiped and a small patch of red blood was on tissue, after that when I wiped was light brown fluid on tissue. No consistent bleeding. I would go to the doctor, but I have no insurance. Can you please help me to understand what is going on? I'm really nervous of being pregnant!
