If you’re a person that has been working out before your pregnancy I believe you can continue doing so (light exercise). But since you’re still in early pregnancy, you might want to take a break for a while. The gestational sac might not be fully implanted to your uterus, still in fragile state. Certain doctors recommended mothers to not move a lot, bed rest, not to lift anything heavy. But after all, the decision is yours. I wish you have a healthy pregnancy! ☺️
