Pelvic Pain

I recently had intercourse on Sunday, and since Wednesday night been experiencing Pelvic pains. No other symptoms but the pains that almost feel like spasms right about the pubic line. Sometimes in the middle and sometimes a little to the left. The first night it was just for 15 minutes, the next day it happened thru out the day (maybe around 10 times) very mild. But TODAY, is a whole different story. The pain is sharper and been happening every 5 minutes. Anyone have suggestions?
