I am taking Clomid CD5-9 with IUI. This month, my doctor put me on Prometrium, even though my progesterone levels were normal last month. My periods are anywhere from 28 - 34 days in length. I took an HCG injection 15 days ago with an UI 13 days ago. Now I am wondering if I should wait for my period to start or take an EPT. If Prometrium will delay my period, it will delay my cycle and therefore, my chances of becoming pregnant sooner. I am 38 and TTC for 1 year. I'm TIRED! So, will progesterone delay my cycle? I don't want to take the test and get another negative result.

Thanks!
