Yes, you have a long road ahead of you. headaches should go away with in a few weeks, but the sickness probably won't till 12 weeks or so. Ginger ale and ginger snaps are good...or a saltine cracker stash by your bed before you get up. just make sure you keep hydrated.
pregnant woman have very low blood preasure, make sure you eat and drink alot of water! i was sick the first 12 weeks and dizzy but it will pass just be positive :)
