Thank you ladies for your comments.
I was not monitored every day by my RE. He told me to come in 24 hours after the positive OPK for an IUI. I am going back to see him on 10/23 which is when my period is supposed to start. I have not had a single ultrasound done so I do not know if the uterine lining and the follicles actually develop the way they are supposed to. This was my 4th Clomid cycle and first IUI. I took a HPT a couple of days ago and it was negative. Maybe it was too early for a HPT, I am still harboring hope that my period is not going to start :)
I am also took 50 mg of clomid this cycle. On day 10 I got a postive OPK. The N.P. said that that cam sometimes happen with clomid. I wasn't o'ing. I just took ovidrel yesterday. My temps are up and down quite often...so I can't help there. Were you getting monitored daily be re?
There are several correct charts I read in a book. Mine used to just go up by .2 or .3 the first two days and go up again thereafter which the book said was normal in some people. You went up by .4 which is completely normal anyhow! Don't worry...you're fine!
