Tiffany

I'm almost 18 weeks. I am a bigger girl. Idk if that matters. 2nd pregnancy with first being a misscarriage. went grocery shopping alone didnt think I just picked up the 40 pound cat litter put it in the cart and then checked out and transfer it to the car.. i didnt carry it more or less transferred it.Got home and husband said please tell me u didn't pick the kitty litter up.. I said yes i did. I wasn't thinking.. Now I'm paranoid I hurt the baby. I wasn't out on any restrictions by the doctor. I haven't had pain or bleeding. Is baby ok? what's ur guys opinion?
