How soon do store bought pregnancy test work?
You sound awfully young. No offense but if you are having sex unprotected then you should be able to read the box of a home pregnancy test which tells you exactly when and how effective it is! Most pregnancy tests do not show a positive until the day of your missed period. Unless you spring for one of the fancy ones which can tell you up to 5 days early. But if she had her period 2 days later well that will answer it for you.
