Sharp pain?!

Hi mummies, it’s my first time expecting and I am in week 25 now. I am experiencing sharp pain at the top part of my bump ; after the belly button. For about 1/2 mins, is it normal? And I do have cramps? Time to time at the right side of my bump. Either slight above the right side , slight above my bump after my belly button height. But no bleeding or anything... should I go and see my gynae tho it’s not my appointment yet? Thank you!!
