3 weeks pp and long walk

Stephanie
Today is gorgeous outside here in socal. I'm so stir crazy from healing and baby not being to be in crowds. I decided to go for a walk with LO (we have been having lots of bad weather). Half way through my 40 minute walk, I started to hurt. I'm not sure if I lifted something or twisted wrong. I walked a lot slower back home and when I got home I felt wet. I had pretty much stopped bleeding so I was surprised to see a bit of blood. It's not bright red or a lot but enough for me to feel it. Has this happened to anyone else? I'm afraid I did damage.
