Is a missed period a sign of possible pregnancy? It might be!
A missed period will probably be your first physical sign of pregnancy. That's because instead of shedding its lining, the uterus is building up its lining to prepare for the implantation of the fertilized egg. Soon after your first missed period, you may also notice that your breasts feel sore and that you're more tired than usual.
