I got an email from the new RE, explaining that the test results came back. All are normal except for the enzyme that metabolizes folic acid. Not necessarily the cause of miscarriage, but it might have played a role. In any case, this is easily overcome by taking 2000 ug of folic acid per day. Not bad at all.
But what has really boggled my mind is getting an email from my doctor. No doctor has bothered contacting me by email ever before.
I like that.
