No period yet? +Other stuff. Pregnant?

maybe you are pregnant..by far best pregnancy test that worked for ME was the clear-blue digital a little on the expensive side but hey it tells you plain and clear yes or no lol ..and when you take this test use the first morning pee becuz it has a higher hormone that senses if your actually pregnant or not.. and the ciggs this early in pregnancy aren't going to effect the child as much right now .. as long as you stop now that you know there is a possibility of being prego then you should be good .. and running as well as walking in the begining shouldnt even be a problem actually walking is the best form of exersise when pregnant besides sex. and the caffiene in your monster not a problem as long as you dont over do anything you will be fine they told me to eat and drink anything but in moderation. im pretty sure none of your activities effected your baby or nonbaby. thing is... is that you still dont know if your pregnant or not and my mother in law had 6 kids and she has ruputed cysts on her overies as well lol as you can see it didnt stop her ;p but as for a misscarrage no i dont thin i dont think you have anything to worry about :) good luck god bless and i hope i helped :)
