Am I crazy?

So my husband and I had sex on one of my fertile days ( not ovulation Day) and we don't use a condom at first, but we do whenever he is about to finish 🤦🏼‍♀️ we want babies but I recently lost my job and we are newly weds ( 5months), but I think I'm pregnant I have felt so nauseous for the past two days, I have been sensitive to smells.. and very fatigued, my boobs don't hurt and my period is only a day late, is it worth taking a pregnancy test or am I just crazy?
