Brown Discharge While Pregnant??

I'm 22 weeks pregnant and started having this discharge. It's more brown in color. I messaged my OB and waiting for him to call me. Thought I'd post to see if any ladies have experienced this before and if everything turned out ok? Just kind of panicking as I had an early loss in July.

Baby boy is kicking around though so I believe he's ok.

I have no cramping and this discharge only shows when I have wiped the past 2 days.
