Pregnancy ?

I have been trying to exercise about 3 times a week for about 2 hours. But my chest has really started to be sensitive and I have been felling really tired. I'm not sure if im pregnant but I was wondering. If I exercise to much could it hurt the baby In the early part of pregnancy. ? Im still waiting for my period to start.
