I don't think its about the calories intake. My gynae says at early pregnancy, it is likely due to chromosomal abnomalities in the embryo when it fails to implant/grow/develop. Don't stress too much about that. Not sure if you'd wanna consider taking maternal milk for better nutrients? I took maternal milk when my nausea kicked in and I wasn't having good appetite. Hoping that you'll have some good news on your next scan. Take care!
did they monitor your hormone level? i did IVF too and have to take hormone blood test weekly to monitor the HCG, progesterone and estadiol till week 8 scan which show the baby is growing well. if your HCG is rising slowly coupled with the slow growing embryo, chances of miscarriage is high. but hope the baby is going strong 💪
this is up to the genetic fusing and cell development. have the proper prenatal vitamins instead of eating more.
hang in there. follow what the doctor says and try to eat comfort food. sending all positive vibes.
