Chemical pregnancy 13dpo...need some love

Well I think I'm losing my BFP (at 10dpo) at 13dpo...looking like a chemical pregnancy. I had 2 positive FRERs (last one was yesterday morning) but my lines on the Wondfo's never got darker over 3 days of testing. This morning I just woke up feeling like AF was coming (as opposed to the past 3 days, I've been feeling like I'd never felt before - bloating, lower back pain, sensitive to smells, waves of nausea, extreme fatigue but also insomnia....). Well a wondfo strip today was completely, snow white negative. Our first month TTC in our 30s and I know I'm not out til AF shows but goodness I'm disappointed!! Please no "shouldn't have tested so early" lectures. Trust me that won't happen again...talk about learning a lesson the hard way. I'm just trying to stay optimistic and be relieved that we can actually get pregnant.
