Had sex four days after my period my period last 7 days the condom broke nd I have been having mild cramping in my lower abdomen could I be pregnan?

Unlikely. If I am interpreting your question correctly, the condom broke about day 11 of your menstrual cycle. Assuming you have an approximate 28 day cycle, you would not be expected to ovulate by then. Cramping likely not due to pregnancy. Take some naproxen or ibuprofen for a couple of days. I expect your period on time; if not, do pregnancy test a week later. Good wishes:)
