Pregnant? Update

Hello everyone,

I haven’t gotten my period in two months. I have taken pregnancy tests but they have all come out negative. I do have a doctors appointment later this month, so I will be asking my doctor. The thing is I have been feeling stressed, but also getting pregnancy symptoms such as: nauseous(no vomiting), more tired then usual, cramps (but no period), and sensitive to smell. But all the pregnancy tests I have taken have been negative. What else can this be? Or has anyone gone through something similar?

Update: I took two pregnancy test and one looks like it has a faint line but the other is negative?? Not sure.
