Last week my CM made me thing I was going to ovulate early and I got a flashy smily face on the Clear Blue Andvanced OPK but no solid face! Im on day 9 of flashy smily faces! And no CM! WTH! I have a 35 day cycle so now i dont even know what to do!!! I just want a child! This isn't fair! Sorry I'm venting!!!! I want to start temping but i dont know if i can start now or i need to wait
