Hi Megsy,
It's definitely implicated with miscarriage and issues during pregnancy.
I know its an issue with heart disease as it causes the artery walls to become sticky and then cholesterol can build up. Not exactly sure how this relates to pregnancy.
Just make sure you are taking plenty of folic acid, B6 and B12 to reduce levels.
There are products out there with all three in one capsule.
Cheers, Lisa.
