Cm changes??

Anyone’s cm still fluctuate in their fertile window? I’ve had watery cm and then every now and then will have thin and stretchy but then back to watery or barely anything. Is this normal? I haven’t reached O day yet (I’m actually not sure when that is supposed to be because I use 2 app and 1 says I’m in it now and the other I’m not supposed to be in it until Friday) I have opks and I’ve got an estrogen surge but no lh yet. So I’m trying to judge from my body and I’m getting discouraged?? Trying to remain hopeful but since my cycle has been a little off this last month in the back of my mind I’m worried I won’t even ovulate . I guess I’m just looking for encouragement.
