Emmalina,
Well, I didn't ovulate, and the follicle, instead of releasing the egg, retained the egg and excess fluid has built up inside the follicle. Most just go away by themselves, mine have in the past, and take about a month or two, sometimes more, sometimes less, its really hard to say what exactly will happen. I'm not really sure if it interferes with the next cycle, that something I have to ask tomorrow at the FS appt (I was a bit upset at the news of a BFN and a cyst that I didn't ask lots of important stuff lol), and yep, its painful, but kind of like a stitch and only if i move a certain way or do certain things that put pressure on that area.

Remember though that I have PCOS, which puts me at a higher risk to cysts and OHSS, and this is the first large cyst I have had in three cycles of treatment so I wouldn't worry too much.
