Blood blisters down below

I’m 37 weeks + 3 days & throughout this pregnancy & with my daughters pregnancy 2 years ago I’ve had blood blisters on the outside of my vagina lips (sorry TMI)

I don’t actually think they ever went in between pregnancy’s, I’m just noticing them more now as they swell & eventually pour with blood!!

Anyone else had this? I don’t want to go doctors & be examined!
