I have been lurking, too. Just too lazy to post anything!
Megarice, I thought the exact same thing. I got my Mirena out on October 1, and I thought FOR SURE I would be pregnant right away. I never ever tried with my other children, and the last one was a big time "oops" (withdrawal...). This time...well, it isn't that easy. Of course, my cycles have been pretty irregular since having the Mirena, and this continues to be the case. I had a 22 day cycle, followed by 33 days, and then a whopping 39 days. I know for sure the last time I ovulated, it was just really late in the cycle. We should have caught it, though...our timing was perfect. But, maybe my lining or the egg wasn't.

So...here we are this month trying again. This will be officially the 3rd month...the first month (which was also the month I had a tubal reversal) we didn't really try.
Brandiesbabies...you asked a question earlier about cycles after removal. I think mine are pretty much the same now, maybe even slightly lighter. They were pretty heavy before the Mirena, and very, very light with it. Now they are mostly in between. I guess it is pretty heavy the first 3 days...I won't let dh dtd with me. Anyway, it is probably different for everyone.
I just wish I would get more regular.
