I'm 26 weeks right now and the "oh, let me help you, don't carry that" drives me nuts. I'll let you know if I need help. I've cut my weightlifting way back, but I'm still pressing 55lbs overhead, deadlifting 90lbs, doing pushups, dips, pullups, I can handle carrying most stuff...
My worst story is the neighbor who told me, as I made my way painfully and slowly out of the house for the first time after my MC to get the mail, that she just knew it was all that exercising she saw me doing and that maybe next time I'll listen to my dr. I should have done the silence thing, but I told her she was completely wrong, he didn't form right, and that my dr was 100% on board with my exercise routine and said it was absolutely not related. I can't hardly stand to look at her. She peeks out her windows at me now as I slowly jog by...I'm always tempted to make a gesture that is not etiquette-approved.
