Ladies... I had my LH surge on CD 15. I think I ovulated that night because of cramps and bloating. Glow thinks I ovulated CD 16. Either way, I'm now I'm CD 18 and my temps haven't gone up. I temp around the same time in the morning, right when I wake up and before I get out of bed every day. What am I doing wrong ? Is this normal? Or does this mean I didn't ovulate?
