Possible twins!!!😃

Michelle? • I have a 3 year old son and just got my bfp for baby #2!!!❤️❤️❤️
Today I had an early u/s and it showed two sacs with yolks in each! I was only measuring about 5 weeks so didn't hear heartbeats yet. The dr said one of the sacs could vanish. Anyone have experience with this? Or anyone else see their twins at 5 weeks and kept both of them with a healthy pregnancy?!
