Anyone have kids close in age?

Did anyone ever get pregnant right after having a baby? I wanna hear your stories, I have my 6 week check up tomorrow and I think I might be pregnant I had unprotected sex at 3 1/2 weeks pp, and again at 4 weeks, I may have gotten my period before I had sex at 3 1/2 weeks because I was done bleeding, haven't been having any symptoms that I'm pregnant but I'm preparing myself just in case.. I'll be able to handle it if I am im ready to start a big family so whatever happens happens. An yes yes I know that your supposed to wait till 6 weeks but I only had a small tear that was healed and done bleeding when I had sex and my doc told me not everyone waits till 6 weeks anyway and it's fine.
