Sex after surgery

First time posting.... So two weeks ago I had both tubes removed laparoscopically. I've had complications with pregnancies including a tubal that needed surgery to be removed. I have two beautiful boys and feel blessed to have them. I knew I was done. The hubby and I have already gone six weeks prior to surgery to make sure I wasn't pregnant and was told to wait up to eight weeks after! Last night we were intimate and only the tip entered vaginally but he did cum inside. I'm not in any pain but I'm scared what could've happened being that we didn't wait. Has anyone else had sex before the doctors limits? If so, was there any infection or anything I should be worried about? I might be over thinking but I am sort of a worry wort so to speak... Thank you if anyone can give some advice to help me!
