... but they said it has to be 5 to be pregnant but the sympyoms i been having are slight sore boobs, dull/slight cramping here and there And i have had a headache for the past few days to and very slight nausea and period is a week late if my cycle is 28 days but i have irregular periods so if my cycle is 35 days then my period is 2 days late. Everything is confusing me. Could i be pregnant? Or what?
