Thanks for the query.
As you do not took the pills according to the recommended schedule complete protection is somewhat doubtful.
Symptoms could be due to side effect of the high dose pills also.
So you wait till your expected date of periods and if you miss the periods, go for pregnancy
Meanwhile you can take symptomatic treatment.
Try to use some regular contraceptive
method in future.
