It's understandable to feel concerned when experiencing bleeding and pain during pregnancy. While it can be alarming, it doesn't always indicate a miscarriage. In your case, the fact that your cervix is closed and the ultrasound showed everything was normal is reassuring. However, it's important to follow up with your doctor for further testing to rule out any potential infections or other complications. They will be able to provide you with more specific guidance based on your individual situation. Remember to take care of yourself and reach out for support from loved ones or professionals if needed throughout this process.
