I would take a test...you could probably take it now. Good luck...are you wanting to be pregnant?
you are very young... you should live a little first... Oh god I am having a girl in 4 months and I hope she doesn't try to get pg at 17! haha
wait until at least 3 days before your next period is due or it won't show up on a HPT.....you could always go to the Doctors and have Hcg levels drawn.....are you trying to conceive?
i have the same symptoms but with cramps severe back pain and headache for past week but just spotting and no period i got all neg tests wait a week after you were suppost to get your period then try to test good luck!
