Too early?

I've been experiencing symptoms for the last few days, sore boobs and nausea. I have irregular periods but it seems to be roughly a 40 day cycle give or a take a few days! According to glow I am ovulating now and have been having sex every other day since coming off my period on the 8th November. I don't usually get sore boobs when I'm ovulating, is it possible I could be pregnant? I'm guessing it's too early to test?
