Me and my boyfriend had sex before my period then 5days after my period waz over we had sex an now I have two of the synthoms fatigue and sore breats its only been a couple of days since I have felt lik this I'm I pregnant? Or should I wait tel da 16 to see if I see my nxt period?

You should just wait you probably won't experience signs of pregnancy until your are a couple of week along! If you are not ready for a baby, you need to use protection! Best wishes!~

You would need to wait until you are closer to when your period is due to try a test... for some women they won't get an accurate result for several weeks. See what happens with your next period and test if need be.
As trying4babykirk said, if you don't want to become pregnant, be sure to use protection every time you have sex... there is no 100% safe time to prevent pregnancy. If you are hoping to be pregnant... hope it turns out how you would like it to.
