HI there...I had my lmp Jan 9th. For the last week and half i have had small cramps...I had unprotected sex the 15th, 17, 18, 19th, and 22. I ovulated around the 23rd. Could there be a chance I am pregnant? I have been trying since October of 2011. It has been 4 months now since I have been off the pill..What do you think my chances are that I am pregnant??
