Please tell me I'm not alone! (TMI warning)

Is anyone else experiencing an upset stomach? I'm a FTM 34+4 and today I keep getting this feeling like I have to go #2 NOW and I only have a few seconds to get to the bathroom. Then when I get to the bathroom, my stool is loose but definitely not diarrhea. It's been happening at least once an hour all day and I usually only go once a day. I see my doctor next week and will be asking about it then, but the office is closed today and this doesn't feel like an emergency.
