Confuse

Hi ladies.. lately i been having mood swings,cravings, I'm always sleepy, and almost everything annoys me. I took 2 pregnancy test both 1 week ago and both of them the 2nd line comes out very faded. Not sure if its positive. 2 months ago i went to the Dr's. Office and he said i was not pregnant. I'm not sure what to do now. I really don't want to get my hopes up and turn out negative.
