I'm 25 years old and been having some symptoms which are worrying me. 
It started in May when I had 2 episodes of stomach cramps and then watery loose stools. Both were treated with Imodium. After this my stools were softer but still formed which cleared up after the second bout of looser watery stool in May. 
I've been fine for weeks and weeks and then on the 11 aug the cramps came again (like period pain but was mid cycle) and again I had a bout of loose watery stool. Took Imodium and been normal ever since until last night when this happened again (am due period in next few days). Didn't take Imodium this time until today when there were again some mild cramps. 
there doesn't seem to be a particular pattern when this happens but as a long time sufferer of a 'lazy bowel' (since I was very very young) going more than 3 times a week is not normal for me and especially not when it's loose and watery. 
I have always had traces of mucus in my stool ever since I was young which is due to the stools being very very solid (normally!) when I go. It won't be every time I go though and there has never been any blood etc. 

Are these 'episodes' that I've had with the cramps just random or could this be something more? As stated above the pain is across the lower abdomin and comes in waves and cramps (like period pain) and is releaved by going to the toilet. Obviously whenever you search anything it brings up cancer as an option so wanted any advice I can get especially with it being a bank holiday!
