Paranoid please help!

Angela

So last Wednesday I took multiple at home tests and all came back positive. I scheduled an appointment and go on the 30th if may. This is my first and I am super paranoid so today I took another test and it came back negative 😳 help please! Should I go buy more home tests? It says based on my last period I’d be 5 weeks and 5days. Anyone else had this happen?
