fraternal to identical twins

i have fraternal twins po clear nung first few weeks. mga sunod na ultrasound po malabo na po yung hiwalay ng sac unless pgsinabi ko fraternal tsaka nila naddetect. mas ok po kung san po ginawa ultrasound dun po kau ult para may basis sila

hmmm twin mom here nag fuse together ba ang placenta? also alalay lang kasi iniiwasan ung twin discordancy when malayo size ng isa vs the other one. take extra care po
