Worried

My fiancé was home for little over a week for Christmas and we were intimate quite a lot. A few times during my fertile window but used protection and twice without (pull out) . I've learned it wasn't the safest thing to do because it's not as effective (I'm not as sexually experienced as one might think so I'm not super knowledgeable on these topics.) My period was supposed to hit 6 days ago (tomorrow marks a week). It usually is only late by 2 days at maximum. I've felt extremely sick and not myself the past few days and took a test yesterday. When should I take another one? Don't leave rude comments, just worried that's all.
