Briefs used during pregnancy


I heard that during pregnancy you should only use cotton underwear and avoid all kinds of g-strings, tangas and thongs.That larger briefs like brazilian and boyshorts would be better.

As I have a big bum, I've always felt more comfortable wearing thongs, as they don't slip and get "into the drawer".

I'm 10 weeks pregnant now, no bump yet, but thinking if I should get new panties...

Anyone has ever faced the same problem?
