IBS cramps or labour pain?

🌈 PM

How do I tell the difference? My IBS cramps come in painful waves that are intensely painful before going away for a short period. I am experiencing this pain right now, but I can't seem to tell if my stomach is tightening with the cramps or if it's coincidental. At what point do I decide it's labour pain and not IBS? Anyone else experienced IBS pain and labour pain have any advice?
