So my last 2 months on the exact same day (the 28th) I had painful ovulation cramps on my right side which both resulted in bfn. This cycle no ovulation pains, and today should be my highest fertile day. I found iv been quite light headed during the past few days. My local drug store doesn't have any opk and the nearest is 2 hours away and it would be to late to order offline now. Has this happened to anyone?
