It is common for pregnant women to experience difficulty sleeping, especially in the later stages of pregnancy. However, if you are consistently staying up all night and unable to sleep, it may be worth discussing with your healthcare provider. As for going into labor, every pregnancy is different, and there is no exact way to predict when labor will begin. While some women may go into labor around their due date or even earlier, others may go past their due date without experiencing any signs of labor. It's important to remember that each pregnancy is unique, and your body will go into labor when it's ready. If you have any concerns or questions about the timing of your labor, it's best to consult with your healthcare provider for personalized guidance.
