2ww with new symptoms everyday. Please don't be AF

So starting yesterday the 26th is when I really started feeling things. I got bad indigestion and heartburn ( I've only had heartburn like twice in my life) with slight nausea. My CM was creamy like lotion and my cervix is high closed and firm. Now today the nausea is a little worse and continuous I'm tired and have a slight headache cervix is still the same. Over the last 3 to 4 days I've had slight cramps and back pain... 8 days till AF but man I hope I don't see her
