I am currently on Aviane combination hormone pills. I missed the first pill of week three of my birth control pills on May 1 and took it the next day as soon as I remembered. I continued taking the pills as normal and started the inactive pills at the end of the week on Sunday. I started my period early that week around Wednesday due to the low levels of hormones in the pills. I had unprotected sex the same week and am currently freaking out due to breast tenderness, it is May 27. Is there a chance that I may be pregnant?
