Feelings about a second baby

My husband and I have been trying for our second child. We recently really thought we had a positive test. Turns out it was a false positive but in between finding that out- I had a lot of confusing emotions.

Our daughter is 14 months and we had always talked about our children being closer in age. We have been talking about this second baby for some time and how badly we want it and how happy our daughter would be. When I thought I was pregnant, I initially was excited but then started questioning everything.

How would I be able to take care of two children while my husband worked? Would my current daughter miss out on important bonding time? If I was sick this pregnancy, how was I going to manage my toddler? I've been building my business and really enjoy it- would I be able to put that on hold for this second baby? We have such a wonderful life and routine and everything worked out right now, a new baby would completely change things up?

My question- are these normal feelings or do we need to reconsider trying for our second right now?
