Supposed to be ovulating today according to glow and af is due 12th Jan but starting Christmas day I have had sore breasts weeks before af. Last month was the same and I came on 5 days early, the month before that I was 4 days late with no breast tenderness at all which cruelly got my hopes up but got bfn. I don't know what early breast pain means, whether it means I'm already out this month or it has something to do with ovulation. I want to use OPK and stop the confusion and hopefully get a BFP. does using these help getting pregnant quicker?
