Yay, I did ovulate on CD18! I thought I had. The reason for the dotted lines is that I had partial ferning after ovulation. I thought that was weird too, but I don't want to take it off my chart because it did happen. Anyway, I'm happy that I ovulated! :)
This cycle should be about 31 days long, which means my period is due 6/11. That's awesome, because it means I'll be able to get the HSG etc. done before we go away (should be around the middle of June I can get that done).
Now if we could just be successful this time, I won't be needing that HSG after all... What are the chances?!
