Thanks for the query.
Just by symptoms we cannot confirm or rule out the pregnancy
You once go for blood test
If the test comes positive, consult gynecologist and go for repeat scan.
And if you want to continue the pregnancy, start folic acid
prophylaxis from now-onwards.
If test comes negative, you can take tablets for withdrawal bleeding with your doctor's advice.
