Should I retest?

Hubby and I had unprotected sex just before my ovulation and during. He always pulls out but one time, the before ovulation, he wasn't 100% sure he got out in time and may have finished partly inside me for a split second.

Lately I've been having odd waves of nausea. Plus sore breasts, an occasional symptom of my AF. Yesterday had very sore breast, which is slightly unusual.

I was supposed to start my period yesterday but it is still a no show.

Took a test this afternoon. At first I thought I saw the outlines of a positive result, barely there like had to look for it. But I couldn't find it again. So decided it was negative. But I took the test an hour or so after drinking a whole pot of tea, a daily routine of mine.

Should I wait for AF to arrive? Or should I retest with first morning urine?
