TTC for last 7 months. I have been using the clear blue ovulation predictor for the last 3 months and have not detected any LH surges. Cycle is 28-30 days and I bleed for 6-7 days. Start testing on day 10 and continue for 10 days, testing first thing in the morning. Not sure what to think, I haven't been to doctors yet - I know that is probably what I should do at this point. I have one DS, took 6 months to conceive him. Any similar experiences or ideas what this might mean?
