Bfp on 11dpo

Hello,

I received my bfp at 11 dpo, this past Wednesday. I have taken tests every morning since and they are getting darker. I have been taking 1600mcg of folic acid when ttc. Do I continue with this amount, or go down the the 1000mcg in my prenatal?

Also, with each of my previous pregnancies, I suffered from hyperemesis gravidarum beginning at about 5 weeks. I want to avoid Zofran and hospitalization, but it seems like I've tried everything. I have recently discovered unisom and b6. While b6 never really had an impact before, maybe it would with the unisom regimen? Ive read to start as soon as I get my positive hpt, but is it safe so early in pregnancy? Have already begun the bad nausea.

I think I answered the folic q in another thread.

B6 never did anything for me either but some say the Unisom is the part that works best anyway. Soooo many women use it that I believe if it was harmful we would totally know it by now.

Okay, I just wanted to make sure there was no harm in taking it at 4 weeks.
