I started paleo 2 months ago and just recently I have started getting stomach aches.
About a week ago I tried some grass-fed, organic whey concentrate protein powder. It had more lactose than I expected (I wasn't really aware of the difference between concentrate and isolate), and it gave me about a 4-hour stomach ache both times I took it, since I'm (mildly) lactose intolerant. I also got diarrhea about 12 hours after each intake.
So I stopped taking the protein powder. However, last night (2 or 3 days after stopping the powder) I had a bowl of strawberries and blueberries in almond milk -- probably a decent amount of fructose, yeah? I had an almost instant stomach ache -- within 5 minutes of taking my first bite. And today, I just ate a small pear, and got the same stomach ache very quickly. I was not eating on an empty stomach either time.
For my first month or so of paleo, it was beautiful. No stomach aches. My bowel movements were A+. What's going on?
EDIT: I discovered the problem. Egg intolerance or allergy. Cut out eggs and everything went back to normal. High FODMAP foods are totally fine now.

Welcome to the wonderful world of FODMAPs intolerance!
You've identified issues with lactose, and that's good for you to know.
Blueberries, strawberries, and almond milk? Did the almond milk have guar gum (or other gums) in it? Strawberries and blueberries are low FODMAP, but guar gum (personally) fucks me up royally. I need to be careful what sort of coconut milk I buy, for example. I actually find strawberries to be a very gentle form of soluble fiber that I tolerate well. And now pears? Yup, sounds like FODMAPs intolerance. I would watch out for apples, too.
You sound very similar to my own FODMAP issues. I would watch it with the commercial processed nut milks. If you really enjoy them, consider making your own, for example. For pears, I find that if I really am craving them, cooking tends to make them more digestable (and they do go well with some fish, steak, and pork!). Don't fret though - FODMAPs are easy to avoid, and many people who need to avoid them, can have small amounts of high FODMAP food without issue. For e.g., I can tolerate a small bit of cheese without worry.
