Hi, So my cycle is normally 27/28 days, but last month it was 26 days. Anyway, I havn't done many OPK tests previously, but last month using them there was no obvious peak. But this month I had EWCM from CD7 or 8, and we BD on CD 11 and 13. I did an OPK afterwards on CD13 and was delighted it was positive. However, on CD 14 and 15 it was still positive. There didn't seem to be any EWCM, apart from suddenly a lot on CD16 followed later by pains in my side which went on and off for about 10 mins. So now I think I ov'd on CD16, maybe it was delayed...and feel I missed the boat this month. Suppose in future, I should follow the advice and bd after the positive OPK. Thanks for following! x.
