I'm 17 weeks pregnant with twins. After 3 miscarriages we did some testing and found I was positive for lupus anitcoagulant. So.. I got pregnant again and started lovenox right away. We were so surprised to see twins! Anyway, I got really lucky and got the first 4 months of lovenox free because someone donated it to my OB office (she no longer needed it). Now I have a problem. My insurance will only cover $500 worth of perscriptions in a year! I thought it was per each perscription. So of course, I can't afford to pay $1000 a month for lovenox. There is just no way. I've never made it this far in any of my pregnanices so I know this lovenox is working. We also tested the last baby and she had no chromosomal problems. My option now is to start Heparin which I believe runs around $250 a month. I'm so nervous that it won't work as well as the lovenox and that I'm going to lose my babies. I understand I'm probably over reacting but after what I've been through this really scares me. I've tried doing my own research and I can't see to find any good solid information on lovenox and heparin, which is better? I guess I'm just looking for some reassurance from anyone that has had success on heparin. I'm also confused about the different kinds of heparin. I've heard of unfractionated heparin and low molecular weight heparin. I want to make sure I get the right one. I have a Dr appointment next Monday so I plan on drilling him about it. I don't get to see my regular Dr who I really trust this next week. I'm hoping this new Dr knows his stuff! Anyway, anyone every been in the same boat?
