How do you know if your pregnant?

im 17 bout to be 18 I've been feelin like im pregnant an if so im probaly about 8 weeks. but the symptoms I've been gettiin is im been feelin sleepy all the time, I get moody all the time,I just want to lay down all day,sometimes I feel constipated but I always got to go pee out of nowhere,umm I spot like at least once a week but I had my period for about 2 days at but it started before I was suppose to but I havent threw up yet but I feel like I have to but it don't c*m up so am I pregnant? oh my boyfriend feels sick all the time he threw up twice an always eatin doesnt the guys get sick too?

just take a test and c you what happens.
sometime if you 2 are really feelin each other he can get your sickness but you never know what .
casue when I was pregnant I had morning sickness all the time until about 5 month but for about two days I didn't feel nothing then my babydad called my and said he is feeling sick and can't stop going to the bathroom and then after that 2 day I was sick again so I think that it can happen.
GOOD LUCK.

well I feel just like you about a week before my period, on my period and about a week after my period and im 15 lol and a virgin so I cant be preggers
