Ultrasound further along, twins?!

Priscilla • Mummy to 2 beautiful boys, ttc our 3rd this year but had 4 miscarriages, finally got another BPF in November and we are due our baby mid 2015 :)
I had a ultrasound yesterday at 4 weeks 1 day, sack measured 5 weeks 4 days and possibly twins. Can you see the small 2 dots on either end?
