Pregnancy symptoms

Hi. AF is due in two days. I have been having symptoms of nausea, period like cramps, hot flushes and tingly breasts. But since yesterday my symptoms have gone down but I still have abdominal cramps and nausea feeling. I am afraid I am out this month but I don’t have my typical period symptoms of slippery discharge. I am also having constipation and mild headache.

I am just so confused. I have to wait until my period day and I don’t want AF to visit me at all. This wait is literally the worst.

Do I still have a chance or am I out?
