Hey guys. I'm just after some input/feedback. My partner and I have been TTC since November. I have irregular cycles since going off the pill last April but they have been getting shorter and shorter until an almost normal length (originally 3 months, the last was 6 weeks). According to my last cycle I should be in my fertile period now. I have been using OPK's for the past few months to aid in prediction. This month I have had a few medium-fain lines (never as dark as the control). The last few days the lines are almost non existent. I'm not sure if I ovulated this month or if I just have a bad batch of OPKs. I use cheap ones from eBay, however when I'm getting close I back it up with clear blue digital. All negative.
