I only had three stitches also but for some reason they took six weeks to dissolve. I figured they would've been gone a lot sooner but nope.

I think it really depends on how many you get and the degree of tear. I only had two stitches with my middle and they were gone by week 2

So weird. I only have three. But I'm ready to be healed up! I'm still pretty sore.

Mine were still there at 6 weeks. It's different for everyone

I wanna say mine took 4 weeks? I didn't really check but I'd say 4-5 weeks.
