Thanks for your confirm.
From your history it seems that you are not pregnant.
To confirm pregnancy
you can get a urine pregnancy test kit from a pharmacy and test it at home.
If it comes back negative I will be more sure that you are not pregnant.
If you want to confirm the urine test results, then you can go for Blood test
to rule out pregnancy.
The confirmatory way to diagnose pregnancy is to see it on an Ultrasound
and hear the baby's heart beat.
Hope I helped.
