Well.... birth control tablets in some women cause blood clots.
Do you smoke? Smokers have higher risks for clots when using birth control tablets.
Did you have nitrous oxide as an anesthesia? If so and you were marginal to begin with you could have interferred with B12 metabolism.
So when taking your supplements with B12 in them, be sure to take on an empty stomach... as B12 is not absorbed much at all if any with food present.
The supplements should not cause dizziness. That can be a sign of TIAs in the brain. So I would go to a doctor and get evaluated for that and/or blood clotting disorders. It might be safer if you didn't take birth control tablets. But that should be a topic for you to discuss with your doctor.
