By 6 weeks, your baby's heart — now beating 110 times a minute — has four hollow chambers, each with an entrance and an exit to allow blood to flow in and out of each chamber.
The heartbeat is detectable much earlier, maybe 10 weeks or earlier when your due date arrives, you will be more than ready to have your baby! The first fetal heartbeat typically remains undetectable until somewhere between weeks 9 and 12. That's when a fetal pole, the first visible sign of a developing embryo, can sometimes be seen. For many women, this means you're 4 weeks at about the time of your missed period.
