OPK'S - DO THEY REALLY WORK??

Heather

Hello ladies,

I just really wanted to know thoughts ans experiences with OPK's. This is my first month really trying them out on a set schedule. Started day 10 and how have peaked day 12 through 16 (today) with no solid smiley to indicate ovulation. I have barely seen any CM. I will keep trying but i honestly think i would have ovulated by now. Do these things really work and if so does that mean i am not ovulating at all?? Could be why im still not pregnant. Help please!!
