I've read that while on Crinone, I shouldn't start my period. I've also read that spotting and bleeding is normal when using Crinone after an IVF cycle. But I have not found much information about heavy bleeding (a little more than my average period) with Crinone. I'm 40 and have unexplained infertility. I've had a regular (usually strong and painful, except while on a birth control pill) period for the last 31 years. I've had all kinds of tests, all showing I am within normal. My husband is also within normal. I had a good response to IVF for my age. I can't afford any more complete IVF cycles; however, I was able to freeze 3 healthy looking blastocysts (which will be my last chance to get pregnant, if this one doesn't work). If this current cycle doesn't work, I need to be as well informed as I can before my final try with the blastocysts. Any information, suggestions of alternative ideas that I should look in to, etc. would be very welcome. Thank you.
