TTC NEWBIE AND STRUGGLING

I am new to TTC. I have a 6 almost 7 year old and I got pregnant with her without even putting any thought into it. Since then I have gotten pregnant 4 more times which have all sadly ended in a miscarriage. So long story short I am starting to track my ovulation. I have been trying to get pregnant for about 4 months now with a miscarriage but I wasn’t tracking anything. I do have PCOS and just start metformin this week also. Now I am starting to track and I’m a little confused. My app shows I should be in peak but these are my ovulation tests. All the advice or tips and tricks would be greatly appreciated!
