Am I Going To Be Pregnant ?

So I'll start by saying that me and my boyfriend don't always getting around to putting that condom on... he pulls out when we don't have one though but this month, what i thought was my period came, a whole week early, but it was light (more than spotting but not enough for a tampon) and only lasted a couple days, and i didnt have my usual cramps + bloading + moodiness, just didnt really seem like a period... it is now passed the time when my period was supposed to come, and the real thing is yet to arrive... i got really sick a few days ago, just for a day i had a fever, body aches, and chills, and the day after i got better i was at the salon with one of my girlfriends and i stood up to go to the bathroom and i got really light headed and passed out, and when i came too i was really woozy and ended up throwing up. i've been pretty woozy the last few days, the only food that has sounded good is lettuce, and i just feel really off but i dont know if its just because i've been thinking about this or because i am actually pregnant!! has anybody else had an experience like this??
