Lol it happens to me to in 13 weeks my husband thinks is the funniest thing in the world but it's so annoying it happens when I throw up to .
I've done that through both pregnancies. I use pads so that I don't have to change undies so often.
Lol you poor thing. Dnt worry it will all be worth it. Try doing pelvic floor exercise (kegels) that helped with me
