Peanutter - did you solve the pain, i often get a dull achey weird feeling (sometimes like a baby moving) basically from end of AF till a few days before O! Before falling pg with DS i went to the drs and they gave me an ultrasound/bloods etc and nothing, no cysts or anything!! Since having DS and going off the pil last month to TTC its bac again, so i don't know but you are not alone!
