My DH and I have been trying for a few months now. I tracked my BBT, my CM, and I took OPKs! I never had a single positive ovulation test. I went to my OBGYN and she was going to put me on Clomid due to the fact that we don't know how long we have until my DH is infertile due to Testosterone shots. I hadn't even bought the prescriptions yet, and I had a random feeling to take a HPT. I saw a very faint line about 10 minutes later, so about 4 hours after that I got another positive! I go in for my Sonogram November 18th!
