I had my last period on April 21, 2017 and I missed my period in may. after one week of that I had my pregnancy test it came out positive. then I went to a doc , she took my scan and told nothing is visible. come after 15 days  have a scan on that day.

on the next day I did pregnancy test at home using kit. it shown positive.  and again we did pregnancy test in other place. it was also positive. so we became 100 % sure.  I used too have nausea, tiredness, back pain.
from last two days I was having abdominal and vaginal pain . so today we went 2 doct  and scanning was done and then too nothing was visible. according to me it's my 6week 6 day.

am I pregnant or not? I am so tensed
