Dental help

I am 17 weeks pregnant & am having a dental problem I’ve never had before. Lately my gums have been bothering me, when I brush they always bleed & I keep up with my dental hygiene (brush twice a day, floss, mouthwash). Today I noticed the gum in between my bottom front teeth is detached. I know I need to go see a dentist, I’m just wondering has this happened to anyone else & will it be fine to wait until Thursday to go see one, because that’s the earliest I can go?
