Birth control question.

So, I've just started my <a href="https://glowing.com/glow-fertility-program">IVF</a> cycle by taking birth control. The thing I have a question about though is the fact my doctor is having me take "active pills only" for 6 weeks, with a 5 day break.

Everything I've read online says most people only do BC for 2-3 weeks? Is it maybe because he wanted me to lose as much weight as I could (10-20% of my body weight) before I started injectables?
