I am so embarassed to be posting this, but i have no one else to ask...

The last 2-3 days i have had increased bowl movements, i've gone from being blocked up, to going like 3 times a day.
What does this mean??
Should i be worried?
I don't remeber having anything like this with DS, and don't really have any other symptoms to suggest a tummy bug.
What should i do?

TIA
