Need advice ??? Please

So around 6:30 am this morning i went to go pee, my butthole had this sharp pain, so i went to go lay back down Then my tummy started to hurt like sharp pains all around my tummy, then my hips started to hurt, then the sharp pains went down to just my lower abdomen and then my Vagina and buthole started to hurt. My lower abdomen hurt on and off about two times then it stopped, and my vagina and buthole continued to hurt, but now my tummy is just sore and my butthole and vagina feel sore, but no more sharo pains??? I plan on calling my Doctor but what do you think it could be?? I am 29 weeks and 3 days
