I Have Diarrhea A Bit More Often Than Normal, I

I have diarrhea a bit more often than normal, i think. In a month about 2 to 3 times, sometimes not even once in a month. From today till the beginning of the year i had it 14 times. Usually when I have it, I have it only once that day. After that I don't go to the toilet for about 1 or 2 days and then the bowel movement comes back to normal. I don't have any pain, just sometimes before the diarrhea, when it's on it's way, what's normal i suppose.
Is it normal?
