Body adjusting: to change in hormonal levels. It often requires 2-3 months for a woman's body to adjust when birth control methods are changed or stopped. What you describe could possibly implantation, although it does not sound typical. The timing is also not consistent with implantation which usually occurs ~6 days after conception, which was unlikely to have occurred during a period.
