Feeling yucky and feverish...

Kelly
Hello! I just took another HPT and I got a 2nd faint line, this one was more  easy to see than yesterday's. I'm supposed to get my period Saturday, hoping I don't! Today I felt very yucky and feverish all day. I took my temperature and it was normal. Is it ok, if I'm pregnant, to be feeling this way? This is my first time TTC so I'd like some advice from those who had similar experiences!
