It is common for pregnant women to experience changes in their vaginal discharge throughout pregnancy. Towards the end of pregnancy, as the body prepares for labor, some women may notice an increase in discharge that can be white or yellow in color and thicker than usual. This is usually nothing to worry about and can be a sign that your body is getting ready for delivery.
However, if you notice any other symptoms such as itching, burning, a foul odor, or if the discharge becomes watery or bloody, it is important to contact your healthcare provider as these could be signs of infection or other complications.
As for your baby's head not fixing at 37 weeks gestation, it is not uncommon for babies to engage (or "fix") into the pelvis closer to the due date or even during labor itself. The timing of engagement can vary from woman to woman and even from pregnancy to pregnancy. Your healthcare provider will monitor your progress and determine if any further action needs to be taken.
It's important to remember that every pregnancy is unique and individual circumstances may vary. If you have any concerns or questions about your specific situation, it's always best to consult with your healthcare provider who can provide personalized guidance based on your medical history and current condition.
