My temps are staying high, yet I am 19 DPO, took HPT this morning and it was negative! I am quite sure I ovulated because of a postive OPK and CM. My average cycle lengths are 32 days and am now on CD 35. Is it possible to be pregnant with a negative HPT? I feel like my body is playing a mean trick no me. I just wish I knew one way or the other. Should I get a blood test or just wait it out?
