HELP!

So I'm having so pain like up in THERE and between my hip bones. I don't think I've strained anything, and I know it's not caused from any sexually transmitted diseases. But it's like sharp pains. I'm not about to start, last week was my fertile week, and it's not gas or constipation. I really don't know what this is. Also above my hip bone on my left side but lower than my waist is hurting. I am ttc and idk if this is something to do with that or what is going on. Any tips/suggestions etc are greatly appreciated. Thanks!
