TTC after a miscarriage. Did i miss my surge???

Cenko

Hi i am ttc cycle 4 after miscarriage. I ovulated last month on cd 18 i think. So my last cycle was a bit longer.

This cycle my kid got realy sick so i wasnt aware how days went. Untill on CD 12 i got a light twinge of blood with creamy CM. So i took an LH test n it was very close to a positive i think. To naked eye the lines were very similar.

When i checked in same day night, it was a clear negative. Did i miss my surge??? Is it possible or is it too early to ovulate???

Do i have any chance this month? I am so sad i feel like i am already out this month.
