I should have gotten my period few days ago!

I was sexually active from June 19th to July 3rd and I was on the pill during this time. My boyfriend and I are in a long distance relationship. I was supposed to get my period during the last week of june but I continued to take a new pack of pills to avoid getting my period. I got my period which was dark brown and clumpy on July 13th while I still had three more pills for that month to go. I decided to go off the pill after being on pill for almost a year. So after my period in July I haven't taken my pill and I haven't had sex. I have been really PMSING for the past 2 weeks, I have terrible back ache, I am constantly tired, I was feeling nauseous and I am really emotional lately(these are some symptoms of pregnancy). Today it is August 15th and I should have gotten my period few days ago, I feel like my period is coming and when I check it is a white vaginal discharge which feels like egg white(sorry for tmi), I usually get this few days before my period but I feel like this time it is longer. Is this because my hormones have gone a little crazy because I continued my pills without taking a break or is there a chance I could be pregnant? I hope to hear from you
