Opinions, Thoughts? 5wks+6days

Hello Ladies!!
I got my BFP on the 13th of Jan, I am due on 1st of October. We got pregnant our first cycle TTCing and my first pp cycle since 13-month-old who is still nursing. My LMP is 9 Dec, but I also ovulated late.
We live in Korea and I paid for a visit at a Korean clinic today. They did an ultrasound, but it was maybe just over a minute long- which was fine, I really just wanted to see everything was in the right places! I took video of the ultrasound and DH watched it ask what the other 'sac' was... So, I re-watched it and this what he saw.
Any Ideas?
