Torn on having more children

Okay guys, first I’d like to ask.. was it harder going from 1-2 or 2-3?

I have two children a girl and boy who are almost 18 months apart to the day. I’ve always wanted my kids at least 3 years apart, but I got pregnant on the birth control pill so was unexpected. I’ve struggled this past year with having 2 maybe because they are so close in age? I’ve always wanted 3 kids and still do! But with how hard this hit me in the last year with 2 under 2 I don’t know now. I’m struggling. I did have a more reliable birth control put in (nexplanon) which I have another 2 years left before I need to have it removed and have that time to decide, but I’d like to hear others opinions on whether going from 1-2 kids is harder in general and 2-3 kids is easy or if it’s the other way around. If people had 3 and wished they stopped at 2. Or if people had 2 and wish they would have had more! I have a feeling since I can’t shake the feeling that I want 3 kids that were not done. I’ve heard people say you’ll know 100% if you’re done so want to know if you guys feel the same way!
