Sharp pains above pubic bone area, worried.

Im almost 16 weeks pregnant and I've had on and off sharp pain a little above my pubic bone region, right in the middle. Since about 10/11 weeks I have had trouble riding the bike at the gym, inducing the same kind of discomfort and feeling like I need to pee. Then at about 14 weeks, the discomfort on the bike turned to pain. The sharp pain I get normally happens if I bend over, but isn't it to early to feel that way!? I also feel it if I sneeze and it normally goes away. Today it started and the sharp feeling/pain won't go away. What is going on? Anyone else experience this??
