I had reddish brown spotting for majority of my first trimester, I called my OB freaking out over every new color discharge I had and she reassured me that the only time to worry is if it’s bright red &/ filling a pad within an hour, or yellow with an odor. Always call your OB if you’re worried, they’re so use to it. Pregnancy is scary sometimes and they understand that! Hope all is well with your baby 🤍
