Im around 7 weeks and we have a small kid at home who always wants to be carried. Also the grocery bags and water cans, i keep wondering if im straining myself. How much is too much in these early weeks?
Because of my early complications my doctor told me to avoid all heavy lifting completely. So please dont assume a general limit applies to you. Check with your own gynac, especially in the first trimester.
Light stuff is fine, but avoid heavy buckets, gas cylinders or anything that makes you strain or hold your breath. Bend from your knees, not your waist. If you have any complication history, ask your gynac for a specific limit.
Honestly I just stopped lifting anything that felt heavy and asked for help, not worth the risk. Split loads into smaller trips. Listen to your body, if it strains, dont do it.
