Just curious.

Scarlett • Hello there. My name is Scarlett. I'm 24 years old, married, and expecting my first in March.
As your uterus stretches and expands, is it typical to have a slight brown discharge? I would think so. I'm 16w5d and every time I've wiped today, I see a very light amount of brown discharge. Also, I can feel it being expelled. I have no cause for concern, but since the last two times I had brown discharge in this pregnancy, it became heavy red bleeding. I'm fairly positive that this is a result of the uterus expanding and I think it's normal. Just wanted opinions, thanks.
