Thanks for you query.
I read your query and I understand your concerns.
Following is my reply:
1) If you had your cycles then it is unlikely to be pregnancy
2) If you are shy to go to a doctor, get serum beta hCG
test from a laboratory which will confirm pregnancy.
I hope I answered your query. I will be available for any follow up query you have.
