Here are my symptoms, excessive vaginal discharge which is clear to lite yellow and odorless. It is mucusy and I wake up soaked at night from it. During the day I have to wear a pantiliner and change it often. My last period was Sept. of 2006, due to pregnancy and breastfeeding, which I am still nursing 8 month old. I also have lower back pain, lower abdomen pain that comes and goes and a fullness feeling, like I am going to start my period. All symptoms have been around for months, except the discharge which started two weeks ago. I am also now getting headaches, which I rarely got before. I am also extremely tired. I have taken about four pregnancy test over the last few months, the most recent being a few days ago. They all come out negative. I am also experiencing a lot of pressure like I need to have a bowel movement, even when I don't. What could be going on.
