So sorry to hear your sad news. I have been there and it is not easy. My first pregnancy I had two sacs but lost one and had a healthy girl. (Spotted with this one). My second pregnancy I lost in the 13th week. (Spotted alot with this one.) My third pregnancy I took progesterone shots for the first trimester to reduce the risk of miscarriage and made it to the end with another healthy girl. Maybe when things calm down a bit and you are back on your feet have them just check your hormone levels to see if they are in line. I have always had low progesterone since I was a teenager, had to take it just to finally get my period started at age 20!!!
I wish you the best in the future. A miscarriage is hard and I really feel for you right now. My mother had three and still had 7 kids so you will be blessed with a little one soon.
