Pregnant?

At the time I was to have my last period (2 weeks ago) I had minimal spotting one day and I have always been very regular on the pill. I have since had sore breasts/nipples, heavy abdomen, very gassy, stomach issues from very empty feeling, nausea, and heartburn/indigestion, lightheaded at times, crampy, pulling in abdomen, achy hips and back and increased discharge. If pregnant, which I feel, I would be 6 weeks and still haven’t gotten a positive prego test! Just wondered what your thoughts are.
