Confused!!

So I have irregular periods having mild PCOS and being a bigger girl but generally the cycle is 60ish days long, yesterday was cycle day 64 and I just thought screw it I’ll test it will be negative it always is and did it just to stop my mind over thinking and hoping. I did the test and I got this faint line straight away, I was in shock and started shaking and crying and rang my mum straight away. She told me to go to the shops and get a clear blue test and come to hers and we will do another. I got there and did the test and it was a big fat negative. I tried a digital and saw the dreaded not pregnant and my heart sank. I’m not sure what to do. Should I test again in a few days? Go to the doctor and get a blood test? I don’t know I’m so confused!
