I'm so confused.. I was expecting my LH surge yesterday but didn't get it then and still nothing today. It's only my second month using the ovulation tests and last month I got the positive ovulation test as expected on the right day. I'm not sure what this means .. the updated prediction would make my period about 3 days late, which is not common. I wonder if this is part of the reason I've had no luck in previous months, maybe I'm ovulating later than I thought sometimes ? Any ideas ?
