its been about a week since i had unprotected sex and im supposed to get my period sometime during the next week or two. Im not sure if this is too soon to feel anything but ive been really sic the past 3 days. my boobs are sore im been extremely gassy, i keep getting dizzy spells one of which nearly made me pass out today. ive been nauseaus all day and i keep getting sudden urges to throw up. but the dizzyness and faint feelings are causing the nausea sometimes so i keep eating because it seems to make the feeling go away. but it comes back within the hour. Im just being paranoid right?
