Help me

So I’m 3 days late on my period and I started to notice this since yesterday can this mean my period is coming, I am really bad at this I’m irregular on my period and me and my fiancé are trying to get pregnant I did a pregnancy test 6 days before my period and it was negative then I did another one on the 1st day my period was late and it was negative I think so I’m planning on buying more pregnancy test tomorrow morning, but I’m just a little nervous 😬 because I had a miscarriage about 5 years ago and I’m just do not want to get my hopes up.
