Cervical Mucus

Ok- I was wondering if anyone else has ever experienced this. The first day of my last period was 5/6/06; my period lasted until the 12th. I began having a lot of clear watery discharge along with cramping around the 17th. I then had unprotected sex on the 17th, 19th, and 21st. We did not use the "withdrawl" method. Ever since then I have had continuous stomach cramps and some "strechy discharge" I know that you have the "strechy" discharge right before ovulation, but I have had this type of discharge off and on for about a week now. Even before and now after unprotected sex. Does anyone know if this means that I have not ovulated yet or, could I still have this discharge even after ovulation and if my body is on its way to "conception". Any answers would be helpful.... Thanks.
