Can someone help

Coco • Im coco im 32 TTC with my fiance my 2 babies were both 24 weeks which ended in stillborn waiting on my 🌈 👶🏽👶🏽

Lmp: Nov.17

I started taking opks on cycle day 7 all negative I'm taking first response digital and also some cheap ones off of Amazon I'm charting for the first time this month and also using my fertile microscope I checked my cervix and got this the online brand is darker than the control line but u haven't took a digital opk for this morning

I will also include my chart my question is does ewcm start before u get your positive opk or anything else
