Getting nervous

I'm 24+2 right now and I'm starting to get so nervous for labor already.

I just had a stomach ache all day and (tmi/ gross, sorry) finally went to the bathroom and it was one of those painful ones that make you feel like you're gonna vomit while you're waiting for it all to come out.

If a poop is that difficult and makes me sick, how the hell am I supposed to handle birth?!

I'm also terrified of getting c-section, I really hope I don't need to take that route.
