A bladder infection is actually the most common reason for preterm labor from what I've read! Soooo, yes, even if you don't get into doc about your pregnancy, see your GP monday (or prompt care earlier) about that possible bladder infection! I'm sure you'll be fine...drink gree tea, if you can, as it's been known to prevent UTI. And yes, a UTI could also cause you to spot red or pinkish... take care, and sticky vibes headed your way!
