Ok So I'm pretty confused, I use Clear blue easy digital ovulation tests... I got three days of high ovulation ( Tuesday/Wednesday/Thursday, flashing smiley face) I always look at the test strip when disposing just to watch the test line get darker or lighter just to get an idea. Anyway today I'm having period cramps like I'm totally going to start but I'm not due till the 8th of Oct. What could there cramps be?
