7w3d pregnant with twins via IVF


So I’m 7w3d pregnant with my first children via <a href="https://glowing.com/glow-fertility-program">IVF</a> and had an ultrasound Friday the 27th of Nov. that showed that I’m having twins!! Super excited!!! Went to my Dr. today to have a chat and see what is next in my pregnancy and he said that my babies have strong heartbeats but they’re small in size, which indicates they’re growing slower than expected, in specific 7-9 days late than the size they should be by now. I’m having another ultrasound on the 7th of December to monitor their growth. But has anyone else ever experienced this sort of situation?
