If you have 2 Gestional Sacs and 1 heartbeat at 6 weeks is it twins?

Having two gestational sacs with one heartbeat at 6 weeks typically indicates that there is one viable pregnancy within one of the sacs, while the other sac may be empty or not developing normally. This situation can suggest a potential twin pregnancy where one embryo is not progressing. It's important to follow up with a healthcare provider for further evaluation and monitoring to understand the status of both sacs.
