PP sex

So 6 weeks PP, had second degree tear and stitches, have felt it’s been all healed for weeks with no pain. Had sex last night for first time since, only slight pain at the start but was actually ok, used plenty of lube. My SO asked if I still had stitches and I felt like maybe there were still stitches. The stitches I got were dissolvable. Also, we don’t get a routine 6week PP check by doctors to check that. Just wondering if anyone else had similar experience?
