Love some advice

My last two cycle were 25/26 days. Today is CD28. Having pregnancy symptoms but the test I bought I don’t feel are reliable and getting negatives. I did a digital today but also negative. I heard digital are less sensitive than non-digital. I am using Inito for my fertility tracking. Here is my current numbers for today. My LH is increasing. I used letrozle the last six cycle buts missed December due to timing. This is the first month Inito it showed I ovulated due to progesterone increase. Also my CD21 labs was 10.7. Strong numbers. Any thoughts or feedback? I have gotten pregnant once that ended in a missed miscarriage. It took until cycle day 33 to find out though. Maybe due to my PCOS.
