Question.

So I did the poll further up and everyone said the line should be getting darker on the tests. Basically I took a pregnancy test last week and I got a very faint positive I then took another one the next day and it was still very faint but it was there. I assumed I am pregnant and posted the test on here. Everyone said it was for sure a bfp. For the past couple of days I've had cramping diarrhea and dizziness.  Feeling concerned I took another test today and it was still very faint today I'd be five weeks and three days. 
Basically I'm wondering what I should do? My doctor won't see me til 8 weeks for my first pregnancy appointment. Should I go to the hospital because of the cramping? Or wait it out.
