Yes! Oh my goodness, I had so much cramping the day of and the day after. (Mostly the day of though.) It felt like really bad gas cramps, but I was afraid to let loose or poop because I was afraid that the pressure I was going to leak the sperm out (irrational, I know) so I think that made it worse?
ETA: Still awaiting the verdict on our first cycle. Cramping can go either way later in the cycle, and this early on I'm sure it doesn't really mean much of anything.
