2 miscarriages later(one in January and one in June), I found out I have 2 copies of the MTHFR gene, C766T. I’ve been on supplements and meds for it for about 30 days. My period is 6/7 days late. I took a test a day after missed period , then 3 days after missed period and again on Friday. All were negative 😩. I’m afraid to test again. Anyone have 3 negative tests and ended up being pregnant?! Maybe I tested too soon?
