What to do?

So I need opinions. Me and my boyfriend had unprotected sex while I was ovulating and in my fertile days. I know at least 3 times he did finish in me. Anyways I'm not sure if I'm just looking into little signs more or just never paid attention but I feel like I can smell things more than normal like food. Also I have been loving the way steak smells lately... I'm a vegetarian😐. And my boobs really hurt but I feel like that's just due to my period fixing to start (supposed to be Friday). I took a test last Friday (7 days before a missed period) and of course a negative. I'm not sure if I tested to early or if I'm really not pregnant. I am having normal cramps just not as much as usually when I'm Fixing to start. I have also been super sleepy and tired. Should I retest or wait? Do you think there's even a strong chance I'm pregnant?
