Hi i m 15 weeks pregnant and I ve had quite a bit of nausea since week 5. I ve been taking Navidoxine 1 tablet at night before bed which lessens the sickness to just bareable but If i don t the next day i have terrible nausea with vomiting, and i m afraid its not easing up. My question is for how long can i take the pill or is there a certain amount then i should stop. I ve taken maybe around 30 days worth which is 30 pills, can I keep taking 1 a day or have I reached a limit and when should i stop taking even if I don t feel better. Thank you.
