Pale poop and abdominal pain. Anxious.

Hello. My daughter is 4.5 yrs old. She has been having pale poop on and off. She has pain before passing gas. It was very recurrent earlier. Now it's mostly twice or thrice a day. She also has secondary lactose tolerance. She ha s just been toilet trained and poops everyday now. Sometimes twice. But when she poops the second time, she sometimes says pain in tummy which goes away after pooping or passing gas. She's healthy otherwise. She had a lot of tummy issues earlier. With loose motion and abdominal cramps  and constipation and I had to give her antibiotics and lactihep. That was a month back though. Now she's only on probiotics. If she has spinach her poop is pale  and green cos of the veg. Can I give her digestive enzyme or should I wait and watch.  Please advice. I'm very anxious.  Thank you.
