Help please 🤗

NB •

Had implant out on the 16th November.

AF came 18th November until 25th.

Much lighter AF came again 10 days later (5th-8th December).

Clear blue OPK came up negative yesterday but flashing smiley today.

Can anyone shed any light.. seems odd to have a period so soon after my last one and it was much lighter with no cramps or normal period symptoms
