Help.

I'm devastated. I think I'm pregnant. I wish I am. My first day of last menses was on the 14th November 2018. Till today, I'm about 9w5d pregnant. But on the 16th Jan 2019, I went for my first check-up at KKH. They claim they can't find the "baby" via scan. So they schedule me for another scan on the 31st. I'm scared, nervous, worried......... But I do not have any pain, cramp, spotting, bleeding and such. Anyone been through this before? p/s. I had a unnecessary caesarean on the April 2018. p/ss. My last two menses (sept-oct 2018) was irregular.
