Thanks for posting your query.
The medicines you have taken are likely to decrease the efficacy of your contraceptive
. Now that your pregnancy
test is negative, you can wait for a week for your periods to start. In case the periods do not come then repeat pregnancy test will help in ruling out the pregnancy.
You can also consult your gynecologist who after getting serum HCG
levels evaluated will help in ruling out the pregnancy earlier.
Hope this answers your query. I will be glad to answer the follow up queries that you have.
Please accept my answer in case you do not have further queries.
Wishing you good health.
