Good Afternoon, I Just Have A Quick Question, My Period

Good Afternoon,
I just have a quick question, my period ended a week ago but I am getting the lower unsettled stomach aches I get the day before my period starts, kind of simular to eating too many berries. Ive never experienced this before and at times I feel a slight pain within my vagina. Could this just be related to a change in diet and exercise, I wouldnt like to visit a dr if its not necessary, thank you!
