Help!

So i had sexual intercourse on the 4th and 5th. I was supposedly ovulating on the 6 and I've been fertile. For the past few days I've been nauseous at least 80% of the day, constipated (im never constipated) and I'm bloated so can someone tell me what's going on !???! I know it's too early for a test waiting 2 weeks to do that.
