About Metformin* don’t read if you have a weak stomach

So I’ve been taking Metformin for about 5 weeks now and so far I’ve only had the 💩 from it which isn’t a big deal, I’ve had no throwing up at all while taking it, but this morning I woke up from a dead sleep and I was so nauseous but I thought maybe if I could get myself to go back to sleep I’d be fine... my stomach started hurting so I thought maybe I had to use the bathroom so I go down stairs and in that moment it happened so quick, but I threw up in my bathtub I mean better there then on the floor. Bathtub is currently getting bleached and disinfected now, but I haven’t left my house in weeks and no one that’s been around me has had this so could it be the Metformin I took 10 hours ago? Or something else? Helpppp please. Also too add it’s never made me sick or feel sick for the whole 5 weeks I’ve been on it.
