I'm 43, female, and I've been having weird bowel symptoms for a while, swaying between constipation, the runs, heavy feeling all the time in my bowels, mucus, tender areas on stomach, distension, liver/gallbladder pain for about 6 months now.  I don't like bothering the gp as know how pressed they are so I spotted the home bowel tests in tescos and low and behold it's positive.  I bought some additional ones online just to make sure it wasn't a dodgy test and all positive, on different days. Any idea how accurate they are and what next steps might be? I've got an appointment for late next week and scared to death. We have bowel cancer on both sides of my family.
