Implantation bleeding??

Yanina

I am 12 dpo and last night I had mild intermittent cramping. I had my first positive hpt @9dpo. I tested again today and the test line is getting darker as days pass. But now I’m having some pinkish discharge and I just want to know if it’s normal implantation bleeding or something to worry. Please help!

Today’s hpt (not first urine)
