What’s a good time to take a test?

Tia • I`m in love with cities I`ve never been and people I`ve never met

So, my SO and I had sex the day before I ovulated and he came inside me. And I’ve been feeling super queasy and off this whole week. I doubt its a right time to take a test but my period is in 8 days. Should I wait for my period to come or should I take a test? And when should I take it ? TIA
