I've heard implantation bleed is light. But seriously, how light? I tried to take a pic of the tissue paper but it's so light it barely shows up in picture. I can see it though. Started yesterday evening. Thought I was just having heavy discharge. Not much this morning. Period is due in 6 days. No cramps or anything. Have been quite tired but then not able to sleep at night. Could be why I'm tired during day. Idk. Thoughts?!
