Congrats on your pregnancy. I hope everything goes well for you.

My SIL has to have daily Clexane injections as well after she had 3 early miscariages and lost her beautiful son at 20 weeks. She also has a bicornuate uterus and had to have a stich put in her cervix at 12 weeks. The Clexane seems to be working for her, and I'm sure it will work for you. At least you know that you are doing everything you can to keep this little bubba going strong.
Best of luck and
