Is this an early pregnancy sign?

Ok so i suppose to get my period in 5 days, but just like 2 days ago i was getting spotting. Then yesterday light bleeding. Like light period. Im irregular i usually always get it on 24th or later then the 24th. I would get heavy blood. But ive never get light periods? Could be an early sign? My dad said someone pregnant. Because in the early pregnancies he always crave or get grouchy. He always get it right that someone pregnant.

Edit:

Today he asked me if my sister is pregnant, he didnt ask me cause he knew I got BC but i havent taken it for a great while😟 It was in my bag & we went to the beach it got all wet.
