First of all, congrats to you.
Me too, was in the same situation as you.. Except the spotting part.. As confirmed by the Kandang Kerbau Hospital 24 hours clinic doctor, my baby should be around 5 weeks..
So tomorrow I'll be seeing my own gynae. Well hopefully will be able to see some development & baby's heartbeat.
As for the dydrogesterone, was given the same thing too, consulted my gynae & she said to just continue... ;D
