I took my nuva ring out last Monday, I didn't get my period till fri(I usually get it 3 days after I take it out) then this whole weekend my period has been super light(I was waiting for the red which never came) but I've only had a tampon in.  So, I'm not sure if the tampon contributed to my light period? Or what is going on? I tried googling but idk what to google.  Results: implantation blood, diabetes, old blood.  I just wanna know if I need to be worried
