Don’t know if its implantation spotting or period symptoms!

Hey ladies! So i still haven’t gotten my first period yet. I’m 3months post partum and today was the first time i saw some mucus with a tinge of pink in it... I’m wondering if it could be implantation bleeding or start of a period?? I forget what a period feels like honestly😅😂 I’m hoping I’m pregnant again honestly!❤️ Iv been having sharp dull pains here and there nothing to bad or consistent!! Just curious of what you ladies have been through!!!
