What is this?!

For the past month or longer I’ve had this thing pop up on my hip when I got it checked out the first time the doc said it’s cellulitis they gave me cephalexin and cream to put on it covering it makes it bleed and it pumps blood out I go through 6 things of gauge almost every time the top skin layer comes off it’s tender all around I’m 36 weeks and I’m just scared if there’s something else going on I dont want it effecting the baby has anyone seen anything like this before??
