IBS & child birth

I'm not meaning this as an insult, simply curious. I have both IBS-C and IBS-D, my flare ups are unbearable. I normally throw up during them, sweat, and cry. I was just wondering if child birth is as painful or close? Is it pain in the same general area? or are they completely different? I'd really appreciate it if I get answers from people that have experienced both please.
