4 weeks postpartum

I’ll be 4 weeks postpartum on Friday and the hubby and I want to try oral for the first time in what feels like forever. I had a 2nd degree tear but not many stitches, and I’m not really bleeding anymore. The only thing that kinda concerns me is he accidentally drools sometimes and it goes down into the lady parts. My stitches seem like they’ve healed up, I don’t have pain in my vag anymore just pesky hemorrhoids 🙄 lol. Is it safe??

Also, is it normal for my abdomen to feel sore sometimes? It feels like I did a bunch of crunches when it’s sore feeling. It might be from picking my baby up when I’m laying down in bed but just wanted to see if anyone else had this too.
