Hi,

Since you had your period in october and november, pregnancy may be less likely if you never had another sexual exposure after. However, irregular intake of birth control pills may lead to failure. Your delay may as well be due to the pills you are taking and may not pose any problem. I will however recommend you to take a pregnancy test for reassurance.

Hope I have answered your query. Let me know if I can assist you further.

Regards,
Dr. Mbuomboh Veranso
