Ovulation Kits

Paula
My husband and I have been TTC for about 6 months with no luck, which is really surprising to me since I've always thought I would be Fertile Myrtle. (My period has always been like clockwork. I was on birth control for about 10 years but I have been off of it since July of last year.) I thought that maybe our timing was just off, so this month I got an ovulation kit to help out. I have followed all instructions and so far I have been taking it for 7 days with no LH surge. Glow originally said I was going to be ovulating Thursday, so the test is proving that wrong. Is it possible that I'm just later than normal when it comes to ovulating? When do I give up testing if every test is coming back with no LH surge? Getting discouraged. :(
