I Started Taking A Vitamin B6 Supplement Once A Day

I started taking a vitamin b6 supplement once a day while trying to conceive my last cycle. I read a lot about how it helps increase your cervical mucus. It's a 100 mg tablet. In addition to that I've been taking my prenatal that contains 15 mg of b6. I got pregnant the cycle I started the b6. Can I continue to take the vitamin supplement in addition to my prenatals now that I am pregnant or should I taper off or stop altogether? I'm worried about whether that high level of b6 in the first trimester will be an issue for the pregnancy and developing baby. But I also read that since b6 helps produce progesterone you cannot stop taking it as soon as you get pregnant because your progesterone levels will drop. Please advise. Thank you.
