Mel,

I'm so sorry for your losses.

If your doctor has put you on heparin which is a blood thinner that suggests he found something that causes blood clots. Some examples are Factor V Leiden and antiphospholipid syndrome, both can cause recurrent miscarriages. These are simple blood tests. I would ask him if he's done a full blood work-up and what the results were. If it's one of these then your chances of success on treatment are very good.

If you want anymore info on these let me know, I did a lot of research after our son was stillborn a couple of months ago (I have blood issues).

I hope you can get the answers you need,

Love Rozzie
