Ok.. if stupid me would have read the instructions, i woulda got the answers i was looking for! hehe..
It says to wait 5 minutes and read results. Any results obtained after 10 minutes should be discarded. So my test line was lighter than the control line at 5 minutes so thats reads invalid. But ive started to get EW CM and as i type am getting O pains!

Renstar, mine are more like a constant ache, on both sides of my stomach.. maybe similar to AF pains but rather than being down lower its on the sides. I have a book my sister lent me about trying to conceive a certain sex, and it says some women get them like i do, some others report a sharp pain or twinge at the actual moment of ovulation when the egg burst out of the follicle.. which sounds like what youre getting.
I get the bloating too.. hehe but like you am just wondering if is my belly and ive been eating too much chocolate this month!
Best of luck come september!!!
