TTC post IUD help?

Hi ladies!

I’m feeling like I’m being a little bit crazy since we just started TTC... but I got Mirena remover CD 15, O symptoms CD 16/17 though I also bought a Clearblue Advanced opk kit that day and have just been hitting “high” every day after the first (“low”) (no peak day yet). Now CD21 and I’m STILL registering “high”, and feeling nauseous as heck. Anyone else experience similar post-IUD? Can’t figure out if this is some normal effect of that or if we possibly got *that lucky* right away? Waiting until I’m *supposed* to get AF to take a preg test, but the waiting suuuucks.
