Dull ache in lower stomach and sex hurts

Ilda
Well im at my peak fertility and ive noticed dull period like cramps..plus i seem to be more sensitive when my and my bf are having sex..i used to be able to do doggie style..go all crazy and now even simple missionary hurts its like im getting pounded on the inside..and my bf isn't that big..lol...could this be due to my ovulation? Glow says its my peak so we've been going at it..plus i heard that dull ache or pain on one side means your ovulating..is that true? So now i guess i have to wait at least 2 weeks before I know if im pregnant or not? Well thanks for reading this...
