If you can get some- try magnesium sulphate paste (get it from the pharmacy in a little pot) spread it all over the sore bit and cover with a plaster overnight and the hair should come to the surface to pull out. I used to work in a hospital and a nurse told it it’s the “dogs b******s*” for splinters, Ingrown hairs and any other foreign objects like glass shards for example. As far as I’m aware it’s safe for use in pregnancy ☺️ Failing that do you have anyone that can help get it out for you? X
Just leave it like that for a day or two, or just put a plaster over it and remove it. When it wi get a bit dry, just remove the plaster and allow it to heal. The hair will grow out eventually,
