So my doctor is putting me on birth control pills starting tomorrow in preparation for <a href="https://glowing.com/glow-fertility-program">IVF</a> cycle end of Oct/early Nov. This may be a very silly question but I've never been on the pills before and I don't know which pill to start with tomorrow. I know I'm not suppose to take the "sugar pills" on the bottom row (white pills)but since tomorrow is Wednesday, do I start with 1st week Wednesday pill or do I just start from 1st week Sunday and go on? Or does it even matter as long as I take the 21 active pills for the next 21 days?

Thank you in advance.
