Bending and grabbing

I'm 4 1/2 weeks pregnant and my job involves a lot of bending down crunching my stomach and grabbing things. I emailed my dr to see if I need to be transferred to a diff dept cuz if so I would need a dr note but she said I should be able to do normal activities until later on in my pregnancy. But I've read online and heard that women should refrain from any excessive or activities that involves them crunching their stomach.

What are your thoughts? Have u had a dr give u restrictions this early on if so what?
