When can I test?

My last active pill of my old pack was on the second and I threw up a few hours later. My next pack didn’t get to me until that Sunday. We had unprotected sex I think that Sunday as well, he pulled out but still, unprotected. I’ve been having some weird symptoms but I kept saying it’s too early to test... but I’m now realizing I never log sex and I don’t actually know when else we did. There was once he came on my vagina but not in... idk if it was close enough to my inactive pills to be a problem. When should I test?
