I think I made a stupid mistake today!!

It’s been exactly 2 months since I had my c section (first one)

We are moving and stupid me totally forgot that I just had a c section, and lifted a very heavy furniture about 100 lbs with the help of my sister when my husband got home he got upset and immediately took over the lifting but I’ve had already lifted quite abit, at first I didn’t know why he was so upset then he reminded me of my c section!!! I don’t have any pain but I’m freaking out!

What should I do?

How do you know if your incision split open in the inside?
