Is it worth a pregnancy test?

Samantha

Hi ladies. So according to glow I ovulated on May 9th. I know this app is never truly accurate and I have never tracked my ovulation or the symptoms of it. However I think it may have been close because once a month before my period I seem to have very clear, watery discharge. Anyways! So we had unprotected sex on May 6th (he pulled out) but on the night of May 10th he did ejaculate inside me. We have never used a condom except for once when we first met. My breasts are feeling sore and heavy today but it's also 1 week before my period should start so Im not sure if its worth buying a test or not.
