Thanks for the query.
Though some of your symptoms suggesting pregnancy
, just by them we cannot confirm or rule out the pregnancy.
These symptoms could also be due to some gastrointestinal cause or due to any pelvic infection
So you once consult gynecologist, get examined and go for one ultrasound
to find out the possible cause.
Depending on that you can take required treatment.
