Should I be worried?

Teairah
Hey ladies! Two Quick questions? After having sex how long do I have to wait to take the first response tests? I lost the box for it and now I have no clue when to take it! This is an emergency kind of! Also I have not found a birth control for me yet because I have history of strokes but I do not know what kind of birth control yet because last time I went and talked to the gynecologist they didn't want to put me on anything yet so please no lectures! I know to use a condom but my period is so weird so I always have to make sure every time I have sex! Thank you in advance!😊
