Norethisterone?

Phoebe

I was meant to start on Wednesday and would be starting my first cycle of <a href="https://glowing.com/glow-fertility-program">IVF</a>, but iv been put on Norethisterone to make it start, How long did it take for you to start if you've taken it? Iv got to of started by the 1st December or I'm going to have to wait another 6 weeks (my cycles are every 6 weeks) as my fertility hospital are closed over the Christmas period.
