I'm not sure what's going on with me. My periods are ALWAYS on time. My past periods were 10/6/12 & 11/2/12 and only last 3 days. I was expecting my period on 11/29/12 according to my app. I didn't get my period on 11/29, so I took a HPT and received a faint positive test result. I took another test and received a negative reading. Later that evening when I wiped there was pink on the tissue. My next trip to the restroom revealed a brown substance, no pink. On the morning of 12/1/12, (the day my cycle should have been gone), I saw red blood mixed with a clear slimy substance. It wasn't until that afternoon that I started having lower abdominal cramps. The blood I have been seeing doesn't seem to be my period because its not heavy and it still has the clear slimy in it. I'm not sure what's going on. Is it possible for you to help me? Thanks in advance
