Could I be pregnant

Stephanie

So had what I thought was my period last week which only lasted 1-2 days, but I am now cycle day 10 and have had some spotting just now which is brown/ pink in colour, I’m still very lethargic and my breast are still tender. I have been cramping all day what could it be. Cycles are usually 28 but last month was 33, what do you ladies think.
