Idk anymore

So… I was supposed to start my period on Sunday but it never happened. I know it’s only been two days but my question is (might be dumb), will a period not start if you have a pad/liner on? Cause I put a liner on the night before my period and it will not start. This is the third month it’s happened. It’ll start once I’m fed up with sleeping with a liner on and take it off. I have all the “symptoms” except blood. Does that mean I’m on my period still? Like I have cramps and hot flashes and acne pop ups but no blood. This might be dumb but I’m genuinely confused
