I dont really know whats going on with my body at the moment...

I haven't been on birth control in about a year and a half (before that was the pill)
my last peirod in march was on the 8th and ended on the 13th
I was with my boyfriend.. and had unprotected sex on the 26th of the same month (the night before we just.. *cough* didn't go in on the 25th)

on the first and second of april I lightly spotted.. really light pink blood.. and so I took a test.. probably way to early and it turned out negitive (I had it taken at school) and who knows I probably took it early (on the 9th) on the 10th I took another test and it turned lightly positive.

I've had a few things like having to pee alot..
being sick to my stomach..
a white mucus discharge..
but I dont know if they were self done because I was worried about being pregnant at the time or not.

before hand my lower stomach was cramping up (the week of the 4th - the 10th), I haven't had anything this bad in a long long time and I'm normally really regular for my period.. (was only 2 days late) I started bleeding late thursday night after taking the test, it stopped early staturday evening and hasn't returned as of yet. In what I've known and can remember with my body I've never had a period this short even when I wanted it and now I'm freaking out.

.. I was also somewhat sick thursday and friday nights (I had a 102 fever) and I'm afraid that during that time I may have miscarried.. and I dont know when to test or when is ok to test.. I finally told my boyfriend last night as well and I'm at a loss for words at the moment and dont really know how to feel anymore about all this and I'm afraid to test more or less.

can somebody please shed some light on some of this for me

is there any hope that I might still be pregnant?
