I’m desperate

This is my 4th month ttc and tracking my ovulation.... last month I ovulated like 3 days later than normal (usually cd 14) and this month I have been testing since cd 8

Cd 8 low

Cd 9 high

Cd 10 high

Cd 11 high

(Today is cd 11 and I took the first in the a.m and the second about 630p.m)

Cd 11 low

Also; my cm was just how it should be for ovulation (sticky egg whites) and my cervix is high soft and felt semi open.

What the heck? Is it maybe that my LH wasn’t in a high enough concentrate since I took it this evening? Or did I just straight up not ovulate?

I’m getting more and more discouraged and heart broken, and next month I’ll be away on a work trip so I won’t be able to ttc.

I’m looking for all the help I could possibly get.
