Wondering if anyone can help - I’ve been taking Norethisterone prior to starting IVF, (to bring my period forward), but all my googling (I wish I hadn’t!) comes up with people taking it for 10 days or so. My clinic only told me to take it for 6 days, starting from CD15. I’m worried that 6 days won’t be enough to cause the progesterone crash needed to bring my period on. Anyone else take it for only 6 days? I could contact my clinic, but I don’t want to seem like I’m questioning their methods!
