Hi i am on my 3rd miscarriage and have been researching that progestorone is very important from ovulation through conception until the placenta takes over and a reason for mc can be your progestorone dropping,not low progetorone but it dropping and stress makes it drop dramatically.Now when i am early pregnant i am psycho with mood swings crying,emotional etc so surely my progetorone must really drop! then i have a mc,was thinking this could apply to a lot of us and i am wondering if i have uncovered something ladies??!!!
