Anyone else torn on having another baby?

I have 4, ages 15, 8, 7 and 15 months. My first 3 are from a previous relationship and my youngest is mine and my husband’s together. He wants to have one more which would make 5 kids 😲 a big part of me feels like having one more would complete our family and I would love to do it, but another part of me is hesitant because of the cost and time and work involved in having another baby. I work FT as does he so it would mean a double daycare bill. Plus I usually take on the majority of the burden in cleaning the house, cooking and taking care of the kids because my husband suffers from anxiety and depression at times. So one more child would only add to that and I worry the stress of all that work would put me over the edge. I’m 35 so I also feel like my window to make these types of decisions is closing. Also if we have another I would like him or her to be closer in age to my youngest, so the sooner the better.

At the same time I would also be fine if I didn’t have anymore. I’m just so torn. Does anyone else ever feel this way?
