Blood blister down there 😑

So I’m 28w2d and I had a small lump that bleeds, wont hurt or itch just bleeds. It’s like red and blue color ... super weird lol ... i asked my obgyn and she said its a blood blister ... she haven’t seen it yet but she said I shouldn’t be worried, that are common on pregnancy 🤷🏻‍♀️

Anyone having the same issue? What should I do to not make it worst... it bleeds every time I wipe.
