Support needed :(

Hello all, Lately I have been having doubts that I will be able to get through an unmedicated birth like I’ve always hoped I could. I am 32 weeks today and been having some severe belly pains lately that are just being chalked up to gas/indigestion. They are so painful, last for hours and exhaust me. I am worried if labor is worse than this I will just tap out and ask for an epidural/c-section. Anyone else go through this anxiety or something similar where they made it through? Or is anyone having similar doubts? Support, advice, positive birth stories welcome please :(
