Pregnant? maybe maybe not?

Patient: I think i might be pregnant but I’m not sure, where are some of the symptoms I’ve been having: lack of appetite, headaches every day or every other day, having to pee all the time, cramping or tightening in my low stomach near my pelvic area, itching, heartburn, nausea off and on all day, having difficult sleeping. I’ve been feeling this way since about the 14-16th of October so this month, the first day of my last period was September 26. I have taken a home pregnancy test on October 26 the day my period was suppose to arrive its now October 29 and still no period. Could i be pregnant?
