Hi 1stimer,sounds like everything is getting ready,bub might come a little early,if you are feeling sick and dizzy try to suck on some jelly beans or barley sugar,your blood pressure could be either going up or down as well,just take it easy and make sure you have someone to stay with you,try deep breathing for those sharp pains,wishing you all the very best. PS, don`t foreget to drink water!
