The cramps you are experiencing along with clear discharge is probably due to premenstrual syndrome or PMS. Your menses should start in few days or next day. These PMS symptoms though mimic that of pregnancy but subside once the menses start or ends. Chances of pregnancy are negligible as you are on birth control and have been using condoms as well.
So it is advisable to wait for few days to allow menses to start naturally an for the pain you may consider antispasmodics which are available on prescription.
I hope i have answered your query,
wishing you good health,
