...If your period was only two weeks ago, you would not be pregnant most likely. Your chances are sooo slim. (few women experince their period during pregnancy.) BUT...I can almost guarantee you, that you are in your ovulation phase. That happens about 2 weeks, or a little less, right after your period. And then it's the remaining time,...about 2 weeks, til your next period. Everyone is different. Some people ovulate 10-17 days after their period. But this is normal. It happens to me. My boobs will hurt up until my period shows, and then it goes away, almost immediately. And you have to remember, you are at that age, where you are still regulating. In your teen years, your pd is going to be different, than in your 20's, most likely. Also, I bet you didn't know this, but young girls, when they first start their period, for a while, they may not even ovulate! (Or may not ovulate all the time) ...Which is releasing the egg, to be fertilized. But you are 17... and I would say you are ovulating, and you are just not use to it...To feeling the symptoms. So do not worry! Everything is on track! GL! <3

Oops! i misread your question, I'm sorry! If your pd. was DUE 2 weeks ago, then you may be pregnant. Take into consideration your own personal cycle. Is it normally on time? Are your irregular? Any stress, etc? It would be time to take a test now.
If you are pregnant, then you would not be considered only 2 weeks pregnant. They go by the first day of your last period. So for example...
If your first day of your last period began on March 1st. (and no matter what day it ended...) And you werent suppose to start you pd. say... until April 1st... And say you were preg. Then technically, the dr's would consider you like 4 1/2 weeks pregnant. And it's def. possible to feel symptoms then. Although some women don't start feeling things...like morning sickness, strong urge to pee, etc, until AFTER 6 weeks, maybe up until 8. Some women report not feeling ANY symptoms until late in the 1st trimester, or even 2nd! On the other hand, some feel them supposedly after conception... But it's more of a "gut" feeling... Esp. if they have been pregnant before. So just take a test. And good luck!
