I am homozygous, two copies of the dreaded C gene... never took Lovenox, only baby aspirin. Both RE (from THE top clinic in US) and OB said you don't need Lovenox (and in fact it would be dangerous to take it) as your homocysteine levels were never that high. And, I had a history of m/c prior to achieving success with DE.
It really irks me to see non-medical people here (and elsewhere) telling newcomers to get themselves on Lovenox. This is what a doctor -- and only a doctor -- should prescribe on a case by case basis.
I am living proof - and I know of quite a few other women with a similar story - the Lovenox is not necessary. It may work for some, but it is not a drug that should be taken lightly. It is not 'just' a blood thinner. Even on baby aspirin, I had very serious bleeding during my C-section. I probably would have gotten into some real trouble had I been on Lovenox. I know women who go on it in desperation (which I do understand), but they don't seem to realize that it can be very dangerous to take Lovenox. And the docs who prescribe it like candy ought to have their licenses taken away from them.
They simply have not done enough research/testing to really understand MTHFR's impact on conception/pregnancy. Newcomers, please do your research before you decide to take Lovenox.
