Starting my second IVF round - birth control

tia

Currently on my cycle day 2, have to start the birth control pill on day 14 of my cycle. When did you all take the pill to start <a href="https://glowing.com/glow-fertility-program">ivf</a> and how long did you take it for? I’ve been told to have it 12 days and then wait for a period for my scans and stims to start.
