Missed LH surge again?

I think I might have missed the surge again even though I've been testing morning and evening! Using Clear Blue with FMU and cheapos in evening. Not got a smiley face with FMU or a dark line with the cheapies. Been testing from CD 11 to 16. Had medium lines on day 12-13 which is when I usually get a positive. However last month it was day 15-16. This cycle days 15- 16 there has been no line whatsover. Only BD twice and now I think it's too late :(

EWCM days 10-12. Sore breasts day 15. I think I may have ovulated already! It's so hard to plan properly like this though, as Glow predicts the fertile week from day 11 onward, but the negative OPKs cause it to be put back.

I really don't want to have to bother with temperatures, as I get stressed enough as it is!

8 months TTC and still can't work out when I'm fertile!

Anyway, rant over!
