I'm estimated to be about 6 weeks pregnant. I went to the Dr yesterday because I was wanting to see if there was anything he could do for me to help me not miscarry so he prescribed me lovonox? I did the first shot last night. He told me it would make me not miscarry. I have had 3 previous miscarriages all very early and I didn't know why. He told me this would help me. I'm 22 years old and married. Is this weird for a 22 year old to be on blood thinners? What do you think?
