Im 20 yrs old and I have 3 day left in my period that I haven't started I took 2 test and both say negative? I have some symp. Such as I'm very tired, tender brest and Im peeing A lot what do I need to do?

So,, let me just see if I am reading this right... you are on your period right now?

Oh wait. I just re-read it again. You said you haven't started. So you are 3 days late? Its not uncommon to be late, or to even occasionally miss a period altogether. However, I would wait one more week, if you still haven't started test again. If still negative, wait one more week. If you still haven't started at that point, it might be time to see a doctor.

You should wait until you have missed your period by at least 1 week, then test using the first urine you pass when you wake up in the morning.
