I haven't had any cramping this time (I've read that cramping can be a good sign of implantation). But, I did experience cramping following my last transfer and didn't end-up pregnant, so who knows? Plus, I'm on an increased dose of progesterone this time that cruelly mimics pregnancy symptoms (enlarged, tender breasts, nausea, etc.), so despite being typically very in tune with subtle changes in my body, I have absolutely no clue.
The one thing that is different this time is that I don't feel not pregnant. In the past, I've always had a feeling, a sort of intuition, when I've conceived. For our first transfer last June, although I had some signs of early pregnancy, I knew in my heart that the procedure had failed. I don't have that feeling this time. So, despite the warning from Nurse Ginger, I have equipped myself with a bulk supply of super-sensitive home pregnancy tests.
I've been sternly advised that I should wait for my blood test scheduled nine days post transfer (thus, six days from now) when HCG (pregnancy hormone) levels are high enough to detect. I've been told (again and again) that testing too early will only drive me crazy, but, hey, I'm there already. So, I plan on using my most concentrated early morning urine tomorrow and releasing the pregnancy-testing Kraken.
