... hormone will enhance any possible pregnancy symptoms I started feeling after I had my IUI proceedure on 2/20/11 before I was told to start the Crinone? I was told my progesterone level was a little low. My second question is that in the event I may not be preggers, is this the type of medication that will delay my monthly friend? I'm due for my period on 3/6 and will go in for a blood test on 3/8 if it hasn't arrived. I'm just wondering if the Crinone suppositories mess with your monthly friend by delaying it. If anyone can help me answer my questions, I'd appreciate it!!! Kristen
