It took me 10 months to get my levels in the feminine range.
Started on e and spiro, got tested at 3 months, not much change. Upped me, checked again, same...upped again, checked, you get the idea.
After that, switched delivery methods, checked, way better but still not good, upped, checked, pretty good.
I say keep at it with the doc, keep checking lvls too. If results aren't better next time, maybe bring up changing methods; some people don't respond well to some (like I don't with orals)
