@littlemelittleu2 First of all: that baby looks AWESOME! So cute and tiny
really proud of you momma.
Second: My family has the MTHFR thing. I mention it 4 times. To a fertility dr. Really highly recommended, my gyn/the one that made my laparoscopy, my 32 years of teaching in my country OB and the hematologist. Every single one of them made this expression of "nah, that's surely not the problem" and told me that was an old stuff, that shouldn't have nothing to do with my losses or a problem.
Here we have stupid assholes with a degree like any country, but we are rated as one of the countries with best medicine and dr.s in the world. So, after I was sure I was being treated by the bests, I believe them with this stuff.
What the hematologist told me was that she was going to run some test that can give me some trouble if they are off, but are the only ones they know for sure can complicate things in a pregnancy. Mostly have to do with Enzymes and blood coagulating at a good time.
I would stick with this guy's opinion. He seems to know what he's doing and being updated. And if your OB send you to see him cause she thought he was one of the best...more reasons to trust him.
Big hugs and again you have an awesome peanut there
