New job found out I'm pregnant

Hey guys I've just found out I'm pregnant and also about to start a new job its physical but it's not got any lifting. Its just a lot of walking daily 3 t 4 times a week of a lot of walking through out my shift in the sun! Would this be ok and safe too do while being pregnant ? I do go to the gym and walk my dogs often it would just mean I would be doing a lot more steps a day through out my day !wouldn't this help me stay fitter through mt pregnancy?
