5 days late/superstition y

I've been feeling more tired then normal, my breast are really sensitive. I feel nauseous at times. I don't know if it's my mind playing games but I'm 5 days late with no sign of my period yet testing negative? Is there hope or em Is my mind just playing games...
On another note me and my mom are really close And a couple of days ago she called me asking if I was pregnant because she was falling asleep when she heard a baby cry and there is no baby no where near. That's exactly how she found out my sister was pregnant before my sister told anyone... lol kinda weird but it kinda gives me hope..
