[|Human|] My doctor didn t tell me that my antibiotics, Tetralysal 300 for my acne stopped my pill, Cerazette from working as a contraceptive. I have heard of friends that it doesn t. Is this true? As I had unprotected sex 9 days ago as I thought it was safe. He did not cum inside me but pre-cum can still have sperm in it I think so should I get a test done? Is it too early for a home pregnancy test? I am really confused. Thanks.
[|AI|]  Hi there, The effect of cigarette which is a newer progesterone only contraceptive is not much affected by tetracycline. If you have taken cigarette regularly there is very little chance that you could be pregnant. Do not worry about the same. The home pregnancy test works if done on the day of the expected next period, if done earlier it can give false negative result. If you are too anxious you could do the home pregnancy test on the next date of expected period. Do not worry, It's very unlikely that you are pregnant. Hope this helps. Regards.
