pregnant?

Hey everyone so my partner and I are ttc. We had sex everyday nearly but have had a break since the 26.08, my period was due on the 13.09 but hasn't come.. It's now the 22.09. I haven't taken a pregnancy test only because I have bee. Waiting thinking it would eventually come but I haven't had any signs of it arriving. tmi I know but I have had white discharge and feeling a little Nauseous every now and then.. Should I take a pregnancy test? :/
