Clexane 20mg anyone?

Hi,

After one missed miscarriage and two chemical pregnancies, decided to get everything checked, and all came back normal except mutation MTFHR Heterozygous. Among other things, doctor has prescribed me 20mg clexane injections daily since positive pregnancy test.

My question is, is anyone here with the same condition taking clexane 20mg? Most people I read about here are taking 40mg and I wonder if I should get a higher dose…

Thank you so much for any answer/advice!
