I am assuming you help lift people, and that probably can not be good when pregnant. I mean a small box here or there would be fine, but people weigh a lot more than boxes. If I were you I wouldn't do it until you confirmed everything. You dont want to strain yourself and put pressure on your tummy area. ↑
during the 1st trimester.. its very critical as the pregnancy is in its most "fragile" stages.. u might want to hold lifting until confirmed by ur dr.. he/she will tell u not to lift anything heavy then :) GL ↑
