So strange

I took a test this morning around 7 am, I threw the test out unfortunately but it was a clear positive, it was pink and it wasn’t even a faint line, so clear that the first response pregnancy test reader, detected both of the lines and said my test was positive. After then, towards the afternoon I went to take a different brand(dollar tree) completely negative. I took a clear blue test the lines were so faint looks almost like an evap line and Walmart 88 cent also negative, even took another FR and it looked so faint looked like an evap. I took another clear blue just 20 mins ago and same as afternoon so faint it looks like an evap line, barley any color at all. Period still not here, no other symptoms but tingling sensation and full breast, pulling/sharp pain in both sides of my ovaries, and diarrhea and no appetite. I don’t know if I’m pregnant or notor Going through a chemical. I don’t know. I set up an appointment with my obgyn but it’s not until 07/07 and it’s a phone appointment for the first appointment. I’ll retest with fmu tmm, is this normal?
