Hi, I'm ttc baby no 2, I started Metformin on the 7th june and I've had 2 periods so far last one being last sunday. Anyway I've been waking up the early hours of the morning feeling sick and when I've got up I've actually been sick! This has happened on 3 separate night now is this the Metformin?? Really don't think I'm preg so soon, I had met 4yo and was fine on it
