Really confused..... can anyone relate?

Whitney โ€ข Married Momma of 3 kiddos 2๐Ÿ‘ผ๐Ÿป and pregnant with our ๐ŸŽ€๐Ÿ’•๐ŸŒˆ ๐Ÿ‘ถ๐Ÿป

So long story short..... thought I was pregnant, HCG keeps going up ( not doubling but going up) had brown discharge a bit of spotting nothing else. Have all the pregnant symptoms, BUT today I go get my ultrasound and they said my uterus is empty and I donโ€™t have an ectopic but do have a cyst on my ovary. WTH is up? Has anyone been through this? Iโ€™m so confused right now. They did bloodwork but Iโ€™m scared itโ€™s cancer. Help!
