if this happens with other symptoms like cramping and bleeding then yes. but if u don't have any other signs then ur safe n things r most probably going well. my symptoms subsided on week 9 so take it easy n don't stress
have a H&H pregnancy!
Nope. Totally normal even during early pregnancy.
Nooooo why would it be a sign you're going to miscarry? You're most likely just paranoid, if it makes u feel better bring it up to you ob.
