TMI!!

Okay so I wear pads cause it's always wet down there and every time I change pads or wipe I see like  a really yellow streak and sometimes it looks like it's mixed with discharge, it doesn't really have an odor to it either .. I'm thinking its just pee. I was just at the doctor April 7th and they didn't see anything wrong with me pee so idk. (23 weeks and 5 days)
