Thanks for the query.
Inter menstrual spotting, breakthrough bleeding
etc are common side effects with the pill.
As you took the missed pill within 24 hours along with next pill the chances of pregnancy
are less usually.
So now you once consult gynecologist take tablets to stop bleeding either in the form of antifibrinolytics
or additional dose of hormones.
As it is too early to decide regarding pregnancy better to continue on pill and if you miss the period on expected date once go for blood test
