Finally pregnant again after 2 losses 😊

I finally got my BFP on a digital this morning 😊 I've had two early miscarriages and I'm terrified of losing this one as well. I've been diagnosed with homozygous c667t mthfr so I've not been taking any prenatals with folic acid and ran out of the ones I could take so I'm hoping a call to a new doctor today will hopefully get me a prescription or something and will hopefully see me soon 😊 as of today I am 3w5d. How are you all managing the anxiety and trying to stay positive throughout your pregnancy after a loss?
