Hi,
thank you for your query.
Yes the changes you are experiencing are due to the changeover from POP (
Progestrone only pill) to Combined pill. because as the pop suggests,it contains only both
estrogen and progestrone,hence to body will take time to get adjusted to it.
these will last for a few days to a week.If it continues for more than 10days then i would advise you to consult an OB/GYN to change over to a different form of
contraception.
thank you,
wishing you good health
