I agree positive is positive. Retest if you need more proof or make a doctors appointment. You can get a false negative but very rarely if ever will you get a false positive. Congratulations!!!!
Probably early, a positive is a positive after all. If you still aren't convinced take another in a couple of days. :) Congrats!
Its probably just really early, test again tomorrow! When I did my first test at 3 and a half weeks it was a faint line but it was there! Good luck!
Faint or not, a positive is a positive!! Congrats!
