I had my tubes tied a month ago and its starting to hurt again...?

I had my tubes tied on October 28th after having my baby boy.It hurt for 2 weeks due to a bad cold that came with a bad cough and everytime I coughed it made the incision hurt(and my insides). Well after 2 weeks it didn't hurt that much but then a week later I was cleaning and doing laundry and when I was takin the laundry down to my washer I felt something "pop" for lack of a better description. I didn't think anything of it at the time until it happened again yesterday and now my insides(behind my incision) hurt. Best way to describe it is it feels like when you tighten your abs. A lot pressure and now the incision site hurts too. The incision site is a bit red also. The incision has been healed for almost 2 1/2 weeks now so its not open/tore open. I'm not sure if maybe I strained myself and caused this or its just normal pains of everything going back to normal. It doesn't feel like period cramps and it doesn't feel like my uterus contracting(or going back to normal after having a baby)...just wanting to get a little insight from ladies that have had their tubes tied and might have experienced anything like this. I have my 6 week check up in a week so I'm just looking for some thoughts or ideas on why it hurts again until I can get to the doctor. Thanks so much.
