sex before 6 weeks?

so im about to be 3 weeks pp in 2 days, last night I got a bit tipsy and things got really heated between me and my husband etc... long story short we had sex (my tipsy brain initiating) and he ____ inside. any insight on this? I don't even know what questions to ask or what I'm looking to hear, i just want some sort of advice and/ or reassurance I guess. anything?
