Had no/barely any bowel movement today?

I normally have a bm once a day. This past week I've been off from school and I've had two BMs a day -normally one at 10am and the second at 2pm. That's not even 8 hours apart. 

Today I barely had one. I had to force it out and when it did come out it was just a small amount. 

I think it's because of what I consumed today. Mainly it was mono but at the end of the day it was a variety of salads and fruits. 

But this week I started school and I have no intentions and I even can't poop in public, I just dislike it. 

Today for real fast I had a few cups of water, like 4 and 8 bananas. Ripened. 

Lunch I had 7 bananas. A bottle of water. 

I got home at two and drank like 4 cups of water and consumed another 6 bananas. (I had 26 bananas total today so I might be a little off during the days break-up)

For dinner I had a bowl Of salad and 6 or so bananas ( i got a bag f dole "greener selection" salad. ) I saw it in my
Local grocery and it was buy one get one free. It's pretty darn good. It has iceberg, romaine, shredded carrots (I know carrots aren't best for digestion) and red cabbage. 
Then my father brought home fruit cups (cantaloupe, honeydew, and orange slice, pineapple, strawberry (1), and pineapple). I had two of these small bowls. (I know oranges and those fruits
Don't combine so I saved the orange for later) 
And right now at night I had another bag of said salad^^

Sorry for the long post, but I was just curious as to why I didn't have much a  BM today and if my mono meals could be the culprit, even though
I know mono meals are probably THE best for digestional problems. 

Thanks :)
