So AF was due today. For the last couple weeks I’ve cried for no reason and sore boobs. Yesterday I bled a little bit and thought Ok great AF started so I went and got a pad on. Well, haven’t had anything since then. Nothing over night and nothing today. I don’t ovulate like everyone else either. I usually ovulate later in my cycles too. I’ve got cramps now so idk if this is implantation spotting or AF just being difficult. I can’t take my Letrozole again until I know for sure I’m not pregnant.
