Welcome to HCM,
Thanks for trusting Healthcaremagic and posting your query.
Spotting for 25 days, is not a sign of normal pregnancy
There are many causes of bleeding per vaginum.
As examination and certain investigations are required for diagnosis, you should consult a Gynecologist in person.
Hope you found my response to your query informative and helpful.
If you have further concerns in this regard, you can submit those with Healthcaremagic as well.
With good wishes,
