I don’t know what to do or think

For the past 3 days i have been getting verrrry faint positives on the strip tests. They don’t seem to be getting darker and it’s so light that when I take a pic it doesn’t show up. I’m going crazy I just don’t know whether it’s really there or whether I am dreaming. I have gone off certain foods and my boobs are soooooo itchy. Never had this (other than with my first) my period finished a week ago although it was verrrrry light. Also having some mild cramps daily. Don’t know what to think. Do I continue to test everyday. Am I pregnant. I do not know

EDIT:::: if not counting my period I would be about 20 dpo if I ovulated when glow predicted! But had positive opks twice last month.
