Peak on CD7 with 26-28 day cyle?

I have been using the Advance OPK for three cycles. the previous 2 I received a Peak reading on CD14 and CD13, this month I received on CD7 (with FMU) after only 1 low reading on CD6 (with afternoon U). my cycles are typically 26-28 days so this seems odd to me. I am not on any meds and do not have PCOS. With the first 2 cycles I didn't even start testing until CD10 or CD11 and would receive 1 High reading before Peak. Do I have a faulty test and keep testing or am I ovulating really early?

Hi Katie - Thanks for getting in touch! We would expect ovulation to occur between day 10 and 16 for a cycle length between 26 and 28 days. The LH surge would typically happen 24 to 36 hours before ovulation. So at the very earliest you could see Peak on CD8. Given that you had see Peak on CD14 and CD 13 previously, we would like to ask you some more questions about how you have been testing so we can validate your Peak Fertility result. Could you please call our careline at 1-800-321-3279 with your test and packing to hand, and mention reference number 001807753A so we can advise you further? We're open M-F 8:30am to 5:00pm.
