9dp5dt… stuck in limbo

So I’m a POAS addict. I’ve been pregnant 6 times, and 5 of those pregnancies ended before 6 weeks. As for my one miracle pregnancy that made it to term- I can’t remember my symptoms or how my lines looked in comparison to my chemicals because I was SUPER sick with Covid and GI symptoms. My husband and I have both had million dollar workups, no answers. Everything always looks “great”. So that brought us to our first FET (PGS) 9 days ago. At 6dp5dt, I got my first positive on a wondfo, but FRER was negative. Decent progression days 7 & 8, though still not dark (I know wondfos can take some time). FRER was a nice positive on day 8 (yesterday) too. I had one episode of spotting when I wiped during a BM yesterday. Then this morning I took one more FRER before my beta. The line was barely there. I’m out of wondfos. The nurse left me a message congratulating me this afternoon because my beta is 55 (they look for at least a 50). I have no idea how my beta is 55 when the FRER was almost white. For some reason, my FMUs are always faintest, but still, I am nowhere near convinced. I will keep taking my meds as prescribed and go for another beta Tuesday. I feel completely hopeless. If this is another chemical (I can feel it in my gut), that will make 6 with no answers… and it will feel even more like my fault and less likely that it’s an embryo issue. Send me all your good vibes and baby dust 💖
