Sour smelling yellow discharge 14 weeks pregnant

I would reach out to your doctor. It may be an infection. Ovia app says this - look out for green or yellow fluid in your panties since it is likely a sign of serious infection. This kind of discharge is usually in a frothy texture and accompanied by a foul odor, so it’s hard to ignore. Green discharge is most often caused by a vaginal infection. These include UTIs, yeast infections, chlamydia, and trichomoniasis, with which the infection passes on to your baby via amniotic fluid. Yellow discharge could be categorized similarly, but you might also see it after sexual intercourse during pregnancy, which is totally normal. Cervical erosion causes many of these infections and is a breeding ground for mucus-producing cells.

Thank you for the information

I'm not itchy. But it's just the smell and color I've noticed

Could mean a problem. I would contact your MD asap.

Sounds like uti possibly. Call your doc
