Could I be pregnant?

Hello, looking for some advice.

Me and my partner have had unprotected sex a few times between the 30th may and the 12th June. I forgot to log them (other than the 30th) .. as you can see it says I should have ovulated between the 2nd -8th, but I’m sure I ovulated the week after, due to the discharge I had.. by what my app says I should have come on my period the 21st (this past Saturday), I’ve been experiencing cramping fine the 20th, but still haven’t came on my period and it’s now the 24Th.. I’ve done a test which was negative.

Could I be pregnant? Or could I have ovulated later? I’ve got no signs of blood and been experiencing a lot more cramps today?

Thank you
