I didn’t start taking a prenatal until about one week after our first month of TTC and by the grace of God we got a positive test this week (3 weeks 6 days today). I feel so dumb that I wasn’t taking folic acid at all until the week i ovulated and not daily until about 3 weeks 1 day. I’ve taken it daily since. Should I be concerned? Don’t eat a ton of enriched foods as we generally avoid heavy gluten meals.
