K.S.
Your body may not be making enough progesterone or you have excess estrogen. It's a simple remedy, just go to a health food store and get some natural progesterone cream and you rub it on like a lotion. We tried for a long time to get pregnant with our first and then I began using progesterone cream and got pregnant within a couple of weeks of using it with our first... and then have had 2 additional babies now as well.
I used the cream on this site. It is supposed to be one of the best. http://www.optimalnaturalhealth.com
