Idk what to do?

The day that i expected my period, I was spotting pink. It only took 1 wipe and it disappeared. That was on the 4th, About 8 days ago and I still don’t have my period. I’m cramping, my boobs are sore, nausea, hungry, etc. I have not tested because last Friday i went to the doctor and they told me it was a negative, that i am not pregnant. They ordered me to do an ultrasound. So just yesterday I had an transvaginal and transabd ultrasound, and the doctor said everything looked normal. I’m confused. Idk what to do. Is there still a possibility I can be pregnant?
