Vaginal pain

I am now 3 weeks pp.. during delivery I had a few minor tears. Nothing serious. So 1 week pp I was feeling great and all my pain had gone and it had been like till today I noticed that I'm feeling some pain in my vaginal area.. I was really worried about my vagina not going back to it's normal size.. which stretched quite a bit considering delivering a small baby. So yesterday I started doing Kegels .. is the pain due to doing kegels or is it something else.. anyone experience this????
