I have had warts both on my toe and on a finger as a child, never while pregnant, but I would image you're more susceptible while pregnant due to your compromised immune system. Warts are caused by a virus and you can get them as easily as skin to skin contact with someone who has the virus. It could have literally been anyone you’ve been around lately. They're really not that big of a deal. They will likely just numb the area and freeze them off and that will be the end of it. I think you can actually get at home kits to freeze them yourself, but I don’t know how well they work.
I have little bumps,but they do not hurt. They do itch a lot!
Do you get little bumps that hurt? I have something similar and didn't know what it was
