I think I’m grasping as straws here. I’ve posted my chart below which looks pretty good to me as my temps are staying up. I had very very little spotting once when I wiped at 7dpo with a little cramping on and off since then. This morning when I checked my cervix it is low medium and closed and I had another TINY little bit of pink mixed with the cm I probably would have missed it had I not wiped my finger on some toilet paper. I’m also have very mild cramping. Could this still be implantation or is AF on her way? As you can see by my chart, I am currently 9dpo and not expected to start until 9/8.
