I'm a 23 year old female and have noticed mucus with a few small streaks of blood in it in my stools. It is usually completely separate to the actual stool which seems normal. I have been to the doctor about this once already and a rectal exam was done along with a series of blood tests. Everything came up normal and I didn't notice anything again for 2 weeks before it started again yesterday. The first time it was white mucus with a small streak of blood in it and now the mucus i've seen appears yellow and there are small streaks of blood in. I have not noticed any blood on the toilet paper or anything like that, it just appears in the mucus. This usually happens first thing in the morning. I had a normal movement yesterday afternoon and noticed no mucus or anything unusual. However when I woke up this morning, it was back again. I usually feel a bit of discomfort in my stomach before it happens, not pain, but it feels like there's too much air in there or something.

Two probably unrelated things but: I suffer from post-nasal drip which has been constant - all day, every day lately, so bad it makes me gag at times. I know that all goes into my stomach too...Could there be an irritation of some sort from that? I also have a pilonidal sinus which has flared up over the past few weeks. It usually doesn't do much which is why I haven't had the surgery on it, but it flares up a couple of times a year.

I'm very scared and my regular doctor is away for a month. For something like this i'd really prefer to see my regular doctor, it would help me feel more at ease.
