Moose-82 • 34, Canada 🇨🇦 Mother to baby Gabriel born February 15, 2018. TTC 5 years with RPL. 5 MCS and 1 NTD. IVF 7 PGS embryos, FET #1 failed, FET #2 June 2017 Immune protocol, baby aspirin, progesterone, HCG injections
My HCG at 4w1d was 175 and today at 4w4d it's 1008! Is that too high an increase or normal? What are your HCGs?
