first cycle of clomid

Tara
I had my progesterone level blood draw on Friday but because of Columbus Day the results aren't back yet. I have a very regular 28 day cycle but it's day 29 and AF isn't here yet. I'm a dork and I forgot to test this morning because I was in a hurry. Do you suggest I test this afternoon and hold my pee as long as possible or wait until the morning? I also haven't had the intense cramps that I usually get about a week before I start. I know that clomid thins your uterus lining (or something like that) so if it didn't get us pregnant this month it at least is making my cycle more bearable. Is that normal?
