OPK frustration

Holly K • TTC #2 since miscarriage January 2016
Ugh..so frustrated! Today makes 8 days of taking OPKs and 8 days of negatives. Today is CD 18 of 30ish day cycles and this is my 4th cycle on Clomid. I'm having lots of EWCM that started yesterday. BDing just in case but I don't think I'll be buying anymore OPKs.
