Help wtf is wrong with me

I’ve been trying for a baby with my husband but then 2 months ago I didn’t come on my period tested when I was 1,4,20 days late nothing. But then this month didn’t come on and then 6 days ago I had light bleeding for 3 days which is weird because I normally bleed half my body when I’m on my period🤣 and normally for 5 days? Help❤️
