Insight please?

Hello!

So I did a test yesterday afternoon and it looked positive + and then I did another one a few hours later that is most definitely negative -

I assumed it might be my HCG levels getting watered down in my urine, so tested this morning which a different test and it was also Negative -

So I’m unsure what to do or think now? Any suggestions? I am trying to book a doctors appointment.

The only side affects I seem to have at the moment are horrendous spotty skin and constant urination.

My period is now 5 days late?
