Spotting 5d before AF?

TMI but me and my husband don’t have a lot of sex usually. This month was an exception. I was not due for AF for another 5 days. First time in awhile was 6days ago. Twice. Pulled out. Then again last night. I woke up this morning with some blood in my underwear. I felt it when it came out and was very confused. Having little cramps but not much. Could it be implantation? Or just maybe had too good of a time last night? 😅 not ttc currently have a 5 yr old autistic daughter that is currently struggling so I am a bit worried with this timing🥲 any advice would be good or
