Pains in my pubic area?

I keep having sharp pains in my area in my pubic area. I don’t drink a lot of water and I did have sex today which sometimes I cramp from. It’s not ovulation as I’m on birth control and it’s a few days before my period. It honestly can be anything. It’s just weird. It starts happening after I pee and last for a little while. Probably is because I need more water.
