Am I pregnant or not?

Okay so I'm going to go into kind of detail so I'm sorry about that haha. But about 2 and a half weeks ago my boyfriend(22) and me(17) had sex. I let him *** in me 3 days in a row and then a 4th time I let him a day or 2 later. I know that would only make me a week and a half at most probably pregnant but I have had early symptoms of pregnancy. I've been nauseous and even barfed a couple of times. Since then. I've had dissiness and I've also been feeling more tired then usual through out the day.
So within the last 3 days I've taken 4 or 5 home pregnancy tests. They've all came back positive, so reading all of that you'd think I'm pregnant huh? But get this yesterday morning I started my period and at that I started it a week early. It's a light one for the most part. I just don't know what this means as of right now my boyfriend thinks I'm not pregnant but I am having doubts any idea's on what it could mean and what I should do?

It may be that you're having an early miscarriage, or you are having pregnancy bleeding.  

If you've had positive home pregnancy tests,  at one point you were in fact,  pregnant.  

Do you still "feel" pregnant?

Honestly? Yes I do.. and yes I did have positive home pregnancy tests I took 4 or 5 of them within like 3 days time. My period is lightening up today and appears to be almost over it's only the third day in.. if that will help anything??
