Unsure of my symptoms?

Karly

Me and my boyfriend have been TTC since June.. I know 3 months isn't a very long time for TTC but my period is due in 3 days and my heart keeps racing, and I can't sleep at nighttime, my boobs are a lot more sore this time around.. I don't wanna get my hopes up on being pregnant. But I'm thinking maybe I should take a pregnancy test, or should I wait and see if my period is late?
