Also forgot to notate that the 1st IUI worked for me..........!!
I had my IUI on 08.26.2009 and got a BFP on 09.09.2009. The most prominent symptom I had was major charlie horse like cramping on my left side. This started 5dpiui. (Super early!) I was actually scared of an ectopic pregnancy. I also had bb soreness, but I am also on Endometrin progesterone which may have caused that. After the sharp charlie horses went away for good, I now experiance some ... soreness? between my "down there" and my belly button. Sometimes a shooting pain from side to side. I had implantation bleeding 10dpiui which I thought may have been my period and the endometrin was stopping her from comeing all the way. Other then that.... seems like the only symptom I have now is sore bb's which I check more often then not to make sure they are still sore like a crazy woman, and excessive sleepiness. Nothing else.... other then the occasional... OUCH! in my belly. Songram is set for 09.25.2009. I will keep you in my thoughts. !
Implantation usually take places around 6 - 10 days after the IUI... You might or might now experience the implantation bleeding... I didn't have implantation bleeding at all and I am 22 weeks now..
The cramp you have were the IUI procedure... don't worry if it's gone... about 5 days before your period... you start experiences boobs sore, tired, just like PMS... but if your period not show up and you still have that symtoms... then it's good chance you are pregnant...
Good luck toyou...
