Tablets to make your af arrive


does anyone know anything about the pills norethisrone, I think that’s near the correct spelling!

I may need them to make sure I get my af in order to do a fet.

how soon can you take them in your cycle? what day?

how many days do you take them for and how many a day?

I do know it takes about 5 days for af to arrive when you have taken the last pill.

many thanks to you in advance. x
