TTC or accidental?

Just a question for you young moms, I’m 21, almost 22, and we’re not TTC but also not preventing. I cramp during ovulation, so I believe I ovulated the 2nd or 3rd. We DTD the 1st & 2nd, but we’ve always used pull-out method until recently. So I’m curious how quick you all got pregnant? The idea has me kind-of excited tbh, but don’t want to get my hopes up. We’re both considered healthy, and fertile- my boyfriend has a daughter already that was an accidental pregnancy. TIA!
