Possible pregnancy

So I got my period last cycle and it was my normal heavy period. That cycle the only thing my partner and I did was foreplay so there couldn’t be a pregnancy occurring.

This cycle I’m late by a day. It was meant to start yesterday and I’m on cycle day 30 now and no period still.

Should I be worried about pregnancy if technically I didn’t have sex last cycle or this cycle and I had a period last cycle.

I also think I ovulated as I had egg white discharge roughly two weeks ago

I also took a pregnancy test on day 6 of last period just to make sure it wasn’t a heavy pregnancy related period.

I just really need some advice as to why it isn’t here yet.
