Am I Pregnant?!

So I am currently not on birth control. I have been off of it for 5-6 months. My periods even after stopping have been on time and regular and has never been late. We currently do not use any protection and use withdrawal. I am currently on day 6 without my period. I tested this morning and it was negative. I am having occasional lower pelvic pressure/ pressure by my ovaries, some constipation, dizziness one day, and increased appetite (as if I was on my period). I have not had any nausea, spotting, or cramping. Do I test again soon? Wait another week or two? Does this even sound like I’m possibly pregnant?
