PCOS & pregnant taking metformin?!

Na

Good morning mommas! I have just a quick question for anyone that has had a similar experience. I was prescribed metformin (850mg 2x a day) back in 2016 and have been taking it ever since for PCOS symptoms of irregular menstruation/ovulation. I was trying to get pregnant so it has helped very much in this process. I am now 6 weeks pregnant and was wondering for those of you who were on metformin and got pregnant, how long did you continue to take your regular dose?

Thanks!
