Lifting too much after gallbladder surgery!!

Had my gallbladder out almost three weeks ago I lifted my 20+ pound granddaughter I was still a little sore but. It bad but now the last two days I have been a little sorer kinda like the first couple days after surgery. It is by my ribcage I called surgeons office and they said it sounds like I could've strained something a little but should be fine they asked how my incisions looked on that side and I told them they still look good not inflammation or anything. So has anyone else experienced this and been ok. And also, I still have a BM about every other day I don't have the "D" like a lot of people experience is this normal. I notice after I have eaten breakfast and lunch by the time it is time for dinner I don't want to eat because my stomach is hard and bloated. Other then being scared to death something is wrong on the inside I feel pretty good. So if anyone can answer my questions I would soooo greatly appreciate it. Thank you!!
