Am I regretting having a 2nd baby

I currently have a 15 month old who is my entire world. I quit my full time job to be at home with him and I love every minute of it. I have my own business and I do get a break a few times a week.

I am 14 weeks pregnant and just not “excited”. I feel like crap, my husband just brought a 6 week puppy home,I have 4 step kids as well as a Velcro 15 month old, and running a small business, and I just feel like I’m already hanging on by a thread, I don’t know if I can handle a newborn.

My first pregnancy I felt such a connection but this one I don’t. What is wrong with me? How do I get out of this funk?
