So this morning, I took a shower and dried off with my white towel, in my morning sleepiness didn't think to look for anything. Fast forward to this evening when I see my towel hanging up and to my surprise, there is a bit of blood dried on the towel. Looks like a good "dry off wipe"s worth. I looked all over myself to see if I had any nicks from shaving this morning, and nothing. Had no bleeding all day as I just noticed this tonight. Currently have creamy cm. sound like IB? I'm 7-8 days dpo and had sharp paint on right side sat and sun....just my luck I noticed the blood 12 hours after it probably happened!
