Positive FIT ( 129) and calprotectin test ( 2861)

Good morning, 

A few weeks back i started getting wave like lower abdomen cramps that made me bend over, couldn't eat for about a week as just didnt want to as felt like it was the food causing the cramps and felt shivery despite the warmer weather and just kept sleeping.  I went to the gp who thought it was Appendicitis which turned out it wasnt. I did mention i think it was h pylori as I have had it before but the pain i had before from that was actually in my stomach and was constant.  My gp said it cant be h pylori as the cramps are lower in my abdomen ( the part between my belly button and pubic area). 

I then started getting loser stools which wasn't uncommon as for months I have had loose stools and mucas in there. This however was very watery and loose and on one day I went about 15 times in 18 hours. 

With this I started to complain more to the gp and got asked to do 3 stoll tests. 

1st test - low and behold h pylori positive, I got told however this wont explain the lower abdomen cramps. 

2nd test - fit test came back as 129ug 

3rd test - calprotectin came back at 2861ug 

Now, I am not worrying as such as I believe its the h pylori that has caused the high numbers. Although again I got told h pylori wont cause that high of a number. But cancer does run seemingly in my family, 5 relatives in the last 10 years have had it, all various types.  I am a 34 year old male with an already dodgy immune system and hypertension. It all just is alot to take at the moment as I feel really run down and am the one having to chase my GP.

Apologise if this does not make full sense, it is 1am and I am half asleep!
