Missed/Lack of Period

Back in Aug i experienced my period. Since then I have yet to have it. Back in Aug. I had it from the 18th to the 23rd. During that time, and about 2 weeks before hand I started having lower abdominal pains which resulted in me going to a urologist, who in the end performed a cystoscope on the 24th of Aug. (the reason was they found traces of blood in my urine before i had started my period.)In the end nothing was ever found to be wrong and it seemed to disappear on its own. Within the past, week to week and a half. I had sex with my boyfriend where we used a condom. As of now I am not on any birth control, because I am taking Paxil(10mg) for my anxiety and it reacted badly when mixed, so my doctor took me off. Now i am experiencing lower back pain, what feels slightly like cramps, random food cravings and nausea, some whitish/slightly yellow discharge, as well as tiredness and trouble sleeping. My concern is could i possible be pregnant or could it be something else? I plan on making an appointment to see my gyno but i might not be able to get an appt for at least 2 month. Any suggestion? Please and Thank you
