Implantation spotting, nothing then bleeding and cramping

La
I just started TTC and in the evening of 7dpo on and off till 9dpo i spotted very light pink. Then for two days I had creamy CM. Then today I started bleeding dark brownigh blood with intense cramps. My AF is due this Saturday the 9th. This is weird! I am regular and gave 27 day clyclrs. Also, my temp is still high. Any thoughts? Please! Im really sad and afraid.
