prolapse ? or cerclage scar tissue??

I just had my third child 11 weeks ago. About three weeks ago my husband said he felt a lump inside me. At First it felt like a large bulge on the inside of my vagina. Now I think I can feel somthing coming down from the top of my vagina.I have never spent much time feeling around in there so I am not sure what is normal. I had a cervical cerclage at 23 weeks with my pregnancy and am wondering if it could be scar tissue???
