I checked CM and CP too and once you record one cycle, you will notice the differences in consistency and position. If you can't reach your cervix, try laying on your back and bending your hip/knees into the dreaded Pap smear position.
AFM I caved today and POAS. BFN. I'm 10DPO, so I know there is a little sliver of hope but I guess we'll find out in a few days when I go in for bloodwork. This is getting really frustrating. I know I'm only 2 IUI's in but I'm not sure how many more of these TWWs I can handle emotionally.
