Anyone else "taking a break"?

We recently had a miscarriage and after meeting with my naturopathic doctor we've decided to stop ttc.  The doctor said, based on my mthfr and other genetic issues, the baby likely didn't make it because my body doesn't allow b12 into the cell. He's given me supplements to "open up the cell" to let it in as it is essential in dna replication. He said 3 months of these supplements  before trying again. So now I'm back on the pill and it's killing me. I'm a poas addict so I feel like I should be peeing on sticks everyday and making this happen. But... We want a healthy baby above all other things so we must have patience. 
Is anyone else taking a break after MC
