What do you think baby #2???

So I had first ultrasound at 6 week. This my first pregnancy, twins travel heavily in my family on both sides. I couldn't hear the hear be but only got see it futter at me. After going home with these pics I notice on side I wonder that maybe possibly of #2. I had vaginal ultrasound it was hard enough to tell for the Dr.
What are your thoughts I have second ultrasound this week.
