Any Have IBs?...

Just curious any have ibs and have had a kid? I am terrified that I won’t be able to handle giving birth.. every time I get an ibs episode it gets to the point I almost want to throw up and pass out and every time I cry because it’s the most pain I can handle. I just don’t think my body could handle anymore pain but what scares me is if my ibs pain is nothing compared to birth. My mother calls them similar to labor pains during horrible episodes but I dont know... I am sad and scared because I want a baby and we are planning to try soon but what if My body can’t handle it I know this sounds stupid but I just wanted to see if there was anyone out there that deals with this and could compare to some extent.
