Anyone else experience this???

It just hit me.
In less than 4 months I will be giving birth to my first child. I wasn't nervous about it until now. I'm really hoping for an all natural birth with no pitocin or epi, but I'm worried I won't be able to go through with it. I've been reading posts/ comments about how unbearable the pain is and it's starting to scare me. I know the next few months are going to fly by... Starting to feel overwhelmed, which is crazy because this was a planned pregnancy. I guess I just didn't realize how close it was. Maybe even closer if she decides to come early. Did this happen with anyone else or am I just overthinking?
Also, any words of encouragement would be greatly appreciated, ladies. I could really use some positivity and uplifting words of encouragement. Please and thank you! 💕 And I'm sorry in advance if this is a silly post. 😓 I'm truly embarrassed for feeling this way.
