I am around 7 weeks and my bras already feel tight some days, then normal other days. I dont know if this starts so early or later only. Anyone noticed this in first trimester?
Usually starts in first trimester itself and keeps increasing till delivery, then again when milk comes after baby. Buy comfy bras a size bigger, dont waste money on fitted ones now.
It increases through pregnancy but the big change for me came right after delivery when the milk came in. Get some nursing bras ready beforehand, makes life easier.
