Ladies!! My cycles are usually pretty regular 27-28 days but this month it was 26 and I started OPK tests on day 14 like usual because I usually ovulate on day 15-16 I tested until day 18 with no positive... I ovulate every month so I'm freaking out and not sure if I missed the surge because it came earlier since my cycle was a couple days shorter this month?!?
