News flash: FETs feel different from fresh cycles. First, with a fresh cycle, there's a kind of build to a crescendo of activity - you're doing shots, you're feeling your ovaries grow, you're getting tests done, then you have the retrieval, then the transfer, then the recovery and wait. With an FET, it's just a whole lot of nothing, then a flurry of activity, then back to nothing.
Which brings me to my second point. After my previous ETs, I felt a great deal going on in my pelvis, since my ovaries were still XXL. Today, I feel just like my normal self (albeit a somewhat estradiol-plumped self). On the one hand, this may make things more agonizing, since it'll be easier to detect symptoms (or, in my case, probably "symptoms"), but on the other hand, since I just feel like my normal self, I keep forgetting that I should even be wondering if I have any symptoms.
I hope those little fuckers implant soon.
