pain during first trimester

So I have this job ths requires heavy lifting. I've been able to do it before but lately I've been getting strong pains in my stomach when moving the boxes. Is this ok and natural or should I go get checked out and maybe get some restrictions?

U shouldnt be lifting anything heavy at all! Go get checked and u deff need restrictions at work. Goodluck

Call your doctor and talk to them, but I know I was told to avoid lifting heavy stuff- including my 4 year old nephew- once I got pregnant.
