Spot on. If you know the hormones involved, the 4 basic stages (Kaplan has it as Follicular Phase, Ovulatory Phase, Luteal Phase, Mensus) and can reproduce those 2 graphs, then anything beyond that will be provided.
I do want to stress that since this is an endocrine process, the mcat will more than likely ask questions dealing with some of the fundamentals of hormonal regulation/feedback regulation along with this. But if they do, they tend to put it in a passage with all the "required" information (read: advanced knowledge) provided and asking you to interpret it using your basic understanding it of it and applying it to the passage/question asked.
Also - know how birth control works. It's simple and is something that's fair game on the mcat.
