Is this normal to have positive ovulation for three days and it just keeps getting darker?!

This was Wednesday

Definitely positive both sides same color

It was also like that one Thursday except later at night it got darker on the test line and lighter on the control line then I wake up this morning and it’s even darker on the test line then on the control line !

The light side is the control line. T

Is this normal ??

Update

Holy crap it just keeps getting darker oh my definitely peek Day!! Didn’t have this last month sooo praying this is our month
