Prenatal vitamins causing stomach pain and bloating? Normal for early symptoms to come and go?

Abby

Since I found out I was pregnant I switched to a higher quality prenatal vitamins. However, every morning after I take them my upper stomach gets painfully bloated that I can hardly stand and it causes backache and some chills. Does anyone else have trouble with this? I had a miscarriage in January so when I have these symptoms it’s really scary, even though I’m almost positive it’s the vitamins because it’s only for maybe 30-40 minutes after I first take them. I’m 5w1d and lately have noticed that my nipple soreness is going away too. Is it normal for symptoms to come and go?
