If you were my patient, I would give you a prescription for
Prometrium to take for 5 days. I like
Prometrium because if you are not pregnant, it will bring on your period. If you are pregnant, and all the tests are somehow wrong, nothing at all will happen.
I would then ask you to wait and see what happens with the next few cycles. Most likely those incredible ovaries will step back up to the plate and your normal cycles will resume. If not, I would start an investigation into why.
