150mg clomid starting day 3 for 5 days. Treated for BV day 15 with 7 day 500 mg metronidazole. My cycle is 28 days now 2 days late nauseous, cramping?

Take a test. If you think you might be pregnant check then check a home pregnancy test. They are cheap, reliable and available at any pharmacy. IF you are taking Clomid then getting pregnant was likely the goal. Since you have missed your period it is time to take a test.
