I hear a lot about constipation. Anyone have the opposite?

Question

I'm 7 weeks tomorrow. This past week I've been having some major tummy\bathroom troubles. Maybe TMI- I've been having the runs or very soft stools. Both smelly. I'm having some cramping (due to that) and then I need to get to the bathroom urgently. I've been going normally up until this past week. I haven't changed my diet. I usually eat pretty healthy. 
Am I alone in this?
[Possible causes for me- I switched to a different prenatal vitamin for a few days but switched back hoping it would ease up. Also whenever I'm really nervous or stressed out, I poop. I'm a nervous pooper lol We revealed that I'm pregnant to our families this week and are in the midst of house hunting so I have been more nervous and stressed.]

Answer

I’m 35 weeks and up until 20 weeks I had mainly diarrhea. Then it switched to mad constipation, but after a couple day’s went back to diarrhea. Most of the pregnancy I’ve been dealing with upset stomach which has been super annoying and no matter what I do, nothing seems to help. 
Only a couple more weeks and then hopefully my body figures it’s shit out. Haha. No pun intended.

Answer

I have a weird mix of both. TMI, I’m constipated for a few days, then I start to have diarrhea cramps & it all comes out. I’ve been feeling bad 80% of the day lol 😭 I’m also taking One a Day prenatal.
