Reason For Lower Abdominal And Groin Pain After Stopping Pill?

Hi I ve been having constant pain in my lower abdomen and groin, I recently came off the pill and have had some excess clear stretchy discharge. The pain is moving from my lower right abdomen, to my right groin, and sometimes around the back, it s a dull and sometimes sharp ache. I m just a bit worried and am awaiting a scan. Sometimes the pains very bad and sometimes it s just nagging. I haven t had any irregular bleeding from anywhere. Thanks for you rhelp.
