i have been have lower left ab pain. dull ache with sporatic sharp pains. urine and bm are normal

I have been having lower left abdominal pain for two days now. Most of the time it is a dull steady ache but sometimes I get a sudden short Sharp pain that almost doubles me over! I finished my period two days ago. I'm not having any trouble with urine or bowels. There is also a full feeling in my lower middle area that's is not painful but is constant.
