possible pregnancy?

hey, this is my cycle for this month so far...

as you can see i’ve had unprotected sex quite a lot this month, every time he has finished inside me. this is my first month off the pill, i have been experiencing some mood swings, tiredness and a little weight gain. i have also had some slight cramping where my ovaries are this morning. just wondered that the chances possibly could be or is it too early to tell? thanks x
