My nerves are everywhere!

I have a 2 year old and a 1 year old and I just found out I’m pregnant with my 3rd 😩

My first two were planned but this one wasn’t ( I didn’t do the right things to prevent it either) but I wasn’t expecting it ig you could say , sound stupid? Sure but

I’m trying my best to let this sink in and cope with it . I’m happy because it’s a baby and I love kids but I’m stressed and nervous because my two kids can be a lot sometimes so I think to my self how will I handle 3 like going places and stuff like that or when they all want attention ect.... sorry I’m just trying to cope and was wondering if anyone had any positive stories or things so say ...
