pregnancy cramps????

So I am 24weeks and 2 days now.. and from last two days I get these cramps in the morning that just come and go.. like 5 minutes cramps.. they usually happens when I cook breakfast in the morning when I have to stand for an hour or so to cook brakfaast and lunch for my husband and me..Am not sure if its something to be worried about as the cramps are quite bearable but still would love advice from all preggers out there if this is normal or not!
