Pregnant. Confused

I recently found out I’m pregnant and I don’t know what to do. I never wanted to have another child but now that I’m pregnant I’m confused on what to do. I’ve been with my child’s father for 10 years and our child is 4. He’s the father of this pregnancy and he said he supports whatever decision I make. He said right now with the timing he doesn’t want another but at the same time he does. I’m in the same boat. I feel so lost. I feel like no matter what I choose I will regret it.
