Headaches

Hello!! I am now 16 weeks pregnant. And I have been having consistent headaches everyday and I've been feeling achy and exhausted. I've been pregnant before but unfortunately I miscarried. This is my rainbow baby so this is the furthest I've been pregnant so I just wanted to know if there was any other soon to be mommies or experience mommies who have gone through this as well. Also I am plus size so I don't know if that plays into it
