Here I am, the night between cd 21 and cd22. I don't know how many dpo I am because I gave up tracking this month. I had o pains about 7-8 days ago. I am having some pretty horrible cramping!! My cycle last mnth was 31 days. It's irregular but never short. If it comes naturally it's between 31-34 days. What could this cramping be? I NEVER cramp like this. Not even when they put in my IUD years ago. We've been ttc #1 for 9 months. This is my 3rd round of clomid. HELLLLLP?!? It woke me up and now I can't sleep cuz it hurts!!
