"no period!!!! Gosh what am I gonna do.. "
well, I guess your gonna do the only thing you can do and that's wait and see and take a test. Don't take that wrong cuz I don't mean it to be snotty or anything. I felt exactly the same way 17 weeks ago when I was worrying about my period coming and it didn't.
Just remember, stress can mess up your period too. I know there's no way youre not gonna stress over it cuz it just doesn't work that way even if youre trying for a baby. But try not to stress too much. I dont know exactly how you do that cuz if youre like me its all youre thinking about and you cant help stressing and worrying. But try, try, try....
Good luck. And let us know what happens. (or doesnt happen.)
