I am having a hard time this month with the OPK. I started femara this cycle...and started testing with OPK on day 11. I have not had a positive surge from day 11- day 17 (today.) Of course the line continues to change in intensity- went from dark to light....but still no surge. Should I stop testing this month? My cycle length keeps changing since my surgery...but this last one was 29 days. WWYD? I dont want to keep wasting them if I really am not going to ovulate the remaining days of this cycle. Could I have missed it? Maybe I should have started testing on day 10? Any insight would be great! Thanks!
ps- when I did OPK when TTC#1 I surged on day 15 of cycle and IUI on day 16.
