Gonal F/Femara question

Kara
I'm CD10 today. I completed 5 days of Femara CD 3-7 and Gonal F 225u on CD 6 and 8. At my scan this morning, I had 12 follicles growing, but only one mature at a 16. Next biggest was 14. Everything else 11 or smaller. They instructed me to do 2 more days of 225u of Gonal F today and tomorrow, back for monitoring Friday morning. The hypothetical plan is to trigger Friday and do <a href="https://glowing.com/glow-fertility-program">IUI</a> on Sunday. I'm very very worried I'll be hyper stimulated...2 doses of Gonal f got me 12 follicles, is there really a chance that 2 more of the same dose won't push me over the edge? Has anyone else had a similar situation and not ended up hyperstimualted? 
I have major trust issues with my Dr...they're the only ones around and they really push <a href="https://glowing.com/glow-fertility-program">IVF</a> and other expensive procedures. They've of course offered that they can take out the extra follicles if I end up hypestimulated...likely at the cost of a couple grand. I feel like they're trying to hyperstimulate me to try and get me to feel like <a href="https://glowing.com/glow-fertility-program">IVF</a> is my only option. 
Any words of wisdom?
