You're welcome! The correct answer is indeed 2. This is a run-on sentence that requires a comma and a conjunction after "2006." Here's how you can correct it:

"The patient had been on oral contraceptives until 2006, but she stopped the Ortho Tre-Cyclen when her husband had his vasectomy."

By adding a comma and using the conjunction "but," you create two separate clauses that are properly connected, making the sentence grammatically correct.
