6 or 7 dpo

I’ve been having mild cramps past 3 days and started to spot a little yesterday morning. It was a little rusty color then transitioned to a light pink/red color. It’s never enough to get to a liner just when I wipe. I used the restroom this morning and it was a little brownish like it’s done for something. I’ve been pretty exhausted the last 4 or 5 days and going to be early, which is not common for me. I’m a ParaPro/Cheer coach at a high school so my energy level is pretty high. 🤣 Now I catch myself yawning by 12 and ready for a nap. 😂 I did at home insemination on the 23rd and 25th while doing opk tests that week. It peaked on the 23rd and was still the same color just not peaked on the 25th. Any thoughts???
