Hello. I have a history of 5 miscarriages usually chemicals. I did IVF for this reason and transferred a euploid. I thought my lines were quite slow to darken so got betas drawn at 5w1d / 22DPO / 17DP5DT and it was 1563. I got a repeat test exactly 48 hours later and it was 2555 ☹️ first scan is next Friday.
