Thanks for the query.
After stoppage of the pill it will take sometime for regularization of the periods.
As you again started pills after one month, it might have led to some hormonal
imbalance leading to inter-menstrual spotting.
If you had any unprotected intercourse
during the pill free period there is possibility of pregnancy
So you once go for blood test
If the test comes negative, you continue with Yaz, the spotting can subside soon.
