should I test or no

Last week my fiancé and I had sex during af. Then right after it stopped. It was 5 days long which isn't normal for me. I normally have a 7 day period. I've been feeling a bit weird too. I've had mild cramping, crazy cravings (fried pickles is all I want this past week), I've had my head in the toilet at least once and still experience long nausea spells, I feel a little bloated as well. Should I try taking a test or wait till af is due again?
