Confused

Adrianna

So I have pcos and I have been on metformin since September I have had cramps for almost a week but no period and my breast have been sore as well so I decided to take a test first it was a dollar store test and it came out positive the second line very faint but it was there so I went and bought a clear blue and again positive but a little faint so I went to urgent care and they did a pee test and they said it was negative all I wanted to was cry this is the closest I've ever been to being pregnant so confused am I or am I not two out of three positive. Any advice?
