So lately I've noticed some symptoms like enlarged , sore breast nipples back aches , cravings , always running to bathroom .certain smells that didn't bother me before are now making me sick. Mild cramping but no bleeding . Ive never experienced these symptoms before

I've always have irregular periods , so when I skipped my June period I didn't think much of it . I'm now 32 days late for my period. 

I've taken four pregnancy test two last week  ,that came back negative.

I took one yesterday , a clear blue digital one  (mid day ) and that one also said "not pregnant" I also had my doctor do a urine test and it came back negative as well . And he said if it's negative then it's negative . 

But then took one  first thing in the morning and I got a faint vertical line 3 minutes after I took it . 

I'm not sure if I should consider it a positive or not because all the other test said (negative or "not pregnant")

It looks positive to me, congratulations happy 9months. You can test again with another brand with first morning urine to see what happens 

My obgyn told me you will never have a false positive so congratulations. Test in a few days to make sure the line gets darker! :)
