Metformin and nausea

Amy

So I’ve been on metformin for well over a month now and on and off but more so the last week or two I’ve been getting intense nausea like so much so it reminds me of when I had Hyperemesis with my first so I’ve been taking pregnancy tests. All are negative. Is nausea an effect of metformin? I haven’t had the shits or anything but this sickness feeling is killing me
