So I have never ever got a + OPK. I am currently using the clear blue digital ones and all my results are O. When I look at the lines there is no progression in the darkness at all Obviously this has led me to do some research and I've found on other forums that women with PCOS don't always have success with OPKs at all. Apparently, some women will never show ovulation on them because of their hormones even if they do ovulate. My doctor is convinced I am ovulating because my period is somewhat regular for PCOS. Do I carry on with the opks or just sack them off when I've used them up?
