Bubbles and white stuff in urine?

Cynthia

So I am 34 and a half weeks. And for the last few days I have had a bunch of white things in my urine and it’s bubbly. Haven’t had it until now so thought it was weird. I know I don’t have a uti or anything because I just finished a 7 day dose of super strong antibiotics for bv that cures all kinds of crap a week ago. Googled it and it says pre eclampsia could be the cause. I was having some problems with my blood pressure going up and I did have some protein in my urine a week ago when I went in to be monitored. Just curious if you guys have had it and what it was?
