so I was at my fertile stage, then I started spotting, I have been spotting on and off for a few days. The spotting isn't bright pink or red. It is darker brown and a few clots with it. I have miscarriage about 1 year ago so I am on the nervous side of things. I also have irregular periods but I'm usually 2-3 days late according to this app. i shouldnt be getting my period for about 10 days. I guess I'm just looking for input on things.
