My rainbow baby brought a stowaway

After 5 miscarriages today we found out we have twins on board! 

Couldn't get a solid lock on both heartbeats, so I'm coming in for another rescan (vaginal this time) on Tuesday when I have my hcg injection. Signs of a yolk sac and foetal pole in each and she suspected a heartbeat on the smaller twin. Says it's nothing to worry about as they've doubled in size and with a tilted uterus it's hard to get a clear picture with a transabdominal.

I'm just in awe. After 5 miscarriages I'm getting not one but two babies...
