Although I was an IVF pregnancy...I did have early bleeding with my 2 previous pregnancys that ended in MC in the 2nd tri. My third pregnancy was a progesterone supported from time of conception till 13 weeks and I had no bleeding what so ever. I rang my obst at 12 weeks saying I had no repeat he made me get last week filled. I'm not too sure with my prog results were as I never had day 21 tests.
Good luck it is best to find someone that is supportive and help you achieve your dreams
