I wonder if anyone can help. I have half-heartedly used OPKs before and never actually got a +, but this cycle, on days 19, 20 and today (21) I have got a v v dark positive. I have got EWCM (lots) although this is much later in my cycle than usual as usually comes up to about CD18 then stops. Does anyone have experience of a +OPK for 3 days in a row, plus lots of EWCM? Does this mean my body is trying to ovulate but failing? BTW my cycle is usually only 27 days long, but I normally OV earlier I think. Thanks in advance.
