Incontinence in pregnancy?

Amanda
I know that some level of incontinence is normal in pregnancy, but when did it begin? I will be 15 weeks on Thursday, and I suddenly felt like I either had urine leak or really liquids discharge leak. Not a lot, just a tiny bit in my underwear. No spotting or anything. I'm starting to freak out because in not sure if it's urine or amniotic fluids or something. Anyone start experiencing incontinence this early? Should I be worried? Thank you for your help!
