8 high fertility days

Christie • 27 y/o Due 11/22/17 after 2 years of infertility. Thank god for IVF. Baby dust and prayers for all ❤🙏🏼👶🏻✨
Hello ladies. I am 26 TTC for 9 months now. This cycle I had 8 days of high fertility before peak finally showed on OPKs. Usually I have several high days before peaking but this was the longest. Is this abnormal? Has anyone gotten pregnant with so many high days? Thanks.
