Cramping at 7dpo

Shannon
I'm current 7dpo. I started spotting yesterday. This morning I woke up with a headache and when I went to get out of bed I had a cramp that made me double over for a few seconds. I never get cramps!!! I'm hoping this is a good sign and I'm having implantation cramps! Any insight? We used preseed this cycle also. Hopefully it did the trick.
