I have been TTC for 2 1/2 years now and with no success. I am currently in my 4th cycle of IUI no luck yet... I'm 7 days past IUI and hoping but not sure what I'm feeling is normal or am I imagining it.... I have had sore breasts since day 3 after IUI and today is 7 days since IUI and I have a slight lower back ache, and few cramps in tummy today, but honest I have felt twinges, cramps, pulses since AF arrived 16 days ago, I think I'm just trying to being hopeful...I wish It would just happen already. 2WW is the worst!
