[ttc #2] TTC since Oct 2011; 1 child; Seattle, Washington 2 posts26th Nov '12
OPK's can 100% be wrong. That's why it's important to chart and temp when you're TTC. That's the only 100% way to know if you've ovulated. It's hard to keep up with sometimes (I've been trying for 15 months now and I gave up awhile ago since I started ovulating regularly and know when I am and the signs now) but it's definitely needed if you are just starting out TTC or have been for a few months and no results.
