I thought I was in the clear

Ugh I’m trying not to be too frustrated with my body! I had my second MC in December and it was natural this time. I had a positive opk at the end of December and in Jan after my first period. I’ve always gotten a positive on CD 10 (I have a 24 day cycle). Now I’m on CD 11 and the line is still barely there. I usually go from a faint line to blazing positive but these are squinters. Trying so hard to just stop testing and BD through the week. Just needed to vent and see if this has happened to anyone else???
