Medroxypreogesterone ????

Okay.... so I’m only 31 have been trying to get pregnant for about two years unfortunately one of my pregnancies has ended in a molar pregnancy followed by miscarriages everything is fine with me and my husband I have two beautiful children I had an HSG done September I had a period October ovulated late this month and have not had a period I went to the doctors yesterday he started me on this medication to start my period because my hCG was negative and my progesterone level was only one has anyone had any experience with this medication 💊 Or any experience not having a period after being a very regular. Person i’ve never had this happen to me I feel like my body is failing me please somebody give me some insight this is taking a toll on me mentally and physically I just don’t understand it!!!!
