Bleeding during pregnancy can occur for various reasons. One common cause is implantation bleeding, which happens when the fertilized egg attaches to the uterus lining. It's usually light and doesn't last long.

However, bleeding can also be a sign of something more serious, such as a miscarriage or an ectopic pregnancy. If you're experiencing bleeding during pregnancy, it's important to consult with your healthcare provider right away for a proper assessment and guidance.

As for constant nausea during pregnancy, it's a common symptom known as morning sickness. It can occur at any time of the day and can be quite uncomfortable. Some ways to manage it include eating small, frequent meals, avoiding triggers like strong smells, getting plenty of rest, and staying hydrated.

Remember, every pregnancy is unique, so it's essential to talk to your healthcare provider for personalized advice and support throughout your pregnancy journey.
