Help please!

Hello everyone, need some opinions or personal experiences please! I know spotting can be anything but help a girl out. First pic if 5dpo and last is today' 8dpo. Has moved from light brown to pink/brown. I had pretty noticable cramping 5-7. Today is not as bad. Never needed a panty liner its basically just dc if "i check". I have a history of low progesterone so im wondering if it looks like AF (doesnt flow til 15dpo). Thanks!!!
