TMI - bathroom question

I'm currently 9 weeks pregnant and I have been making frequent trips to the bathroom for BMs. These past few days I've had nothing but diarrhea. I can pin some of it to the foods I've eaten but it's honestly been 5 days of it. I stay hydrated but it seems like every 15-20 minutes I need to find the closest bathroom. Should I be worried? I don't feel sick or any other type of way but when it's time to go...it's time to go. I have an appointment with my OB on the 24th of this month but I'm wondering if I should call and get her opinion. Ladies I need your help, and I apologise for the over share. But if you have or are experiencing this same situation I'll take any advice!
