Well as far as I know if your baby needs certain nutrients (such as calcium or other things it can get from teeth) then you'll start to probably bleed from your gums (mainly when you brush your teeth) or have aches in your teeth from that. It is normal and I suggest drinking lots of milk to help it go away or take calcium chews
It's normal. Before I got pregnant I never bled from my gums or got random tooth aches and now it's horrible. It's just something that happens.
Your baby takes all the nutrients from your gums So that could be it. That's why I brush my teeth like 6 times a day lol
