anxiously awaiting beta day

I am anxiously counting down the days until the 12th. It's the day that I go in for bw to see if our embies stuck. Each moment of every day since the transfer has been filled with anticipation of knowing. I have experienced cramps on and off since transfer day; sometimes strong enough to make me believe that AF is about to come. So off to the restroom I go, sadly expecting to see blood. But none so far. I search the internet, looking for any answers for why I have cramps. All I can seem to find are other women stating that they had cramping and spotting, which led them to a BFP. But like I stated, I have had no spotting. I have a myriad of pregnancy symptoms...but they can all be chalked up to the PIO injections. So can the cramps. So I am left to wonder, and stew in my bubbling anxiety. I think the fact that I haven't had any sort of bleeding is good, right? But what about the fact that I haven't had spotting? Aren't I supposed to have spotting, to show that my embies are implanting all nice and snuggly?? So even though I have lots of symptoms that can easily be due to the PIO, I will go ahead and list them:
~ intermitten nausea
~ cramping
~ sore breasts
~ mood swings
~ night sweats
~ really strange, vivid dreams
~ hot flashes
~ fatigue, almost feeling flu-like at times
~ increased sleepiness

If you are reading this, please don't jump ahead and assume that I am declaring these as pregnancy symptoms. As I stated, I realize that most of these (if not all) are side effects of the PIO. But also the mind begins to play really mean tricks on a woman who's ttc.
So much more I would like to write, but I am feeling too sleepy to finish this entry now.
