Had an ultrasound today with my gynaecologist and he said he sees two sacks but he can’t say for sure. I won’t find out till

My next ultrasound in 3 weeks. I’m currently 5 weeks 3 days and I’m happy with twins but just super nervous as it is my first pregnancy and not sure if I’m mentally prepared for two babies. What are your thoughts? Can you see two sacs? One to the right of the obvious sac? I am so nervous 😖
