Hello! I am new to the OPK stuff.... was on birth control pills for 5 years and stopped taking them in October. Have been charting my cm and BBT for a few months and TTC.... but no positive results yet! So I started using the OPK strips this month and this was the closest I have gotten to a positive but I'm not sure if it's dark enough!! This is the only positive/semi-positive result I got all month. Thanks for your help!
