Pain near the groin area?

So, let me make this short. I haven’t had a period since July 23-25. Somewhere around there. I felt all the symptoms of pregnancy and decided to take a hpt. Two came out faint positives. And three different brands came out negative. I went and got blood work which also came out negative, about 4 days ago. Today I started getting pains near my left side of vagina area near the inner side of my leg, it’s not IN my vagina but it feels like it could be like the muscle/bone. Every time I move it hurts!! Does anyone know what this could be?

Please help!!
