Constipation? Or something else...help!

Recently I started properly taking my medicine (about two months ago). Then one night I woke up with a lot of lower back/ pelvic pain and constipation....is this a side effect of now appropriately taking my enzymes? It's now moved from my lower back to the front but still constipation.
