Spotting and cramping can sometimes be normal during early pregnancy, but they can also be signs of a potential miscarriage. It is important to consult with your healthcare provider for proper evaluation and guidance in your specific situation. While it is concerning to experience these symptoms, it does not necessarily mean that you will miscarry. Your doctor's advice to monitor the intensity of the spotting and seek further medical attention if it becomes heavier like a period is appropriate. Mild cramps and lower backache can also occur during pregnancy due to various reasons such as hormonal changes or stretching of ligaments in the uterus. However, if these symptoms worsen or are accompanied by severe pain or heavy bleeding, it is crucial to contact your healthcare provider immediately as they may indicate a more serious issue. Remember that every pregnancy is unique, and it is best to rely on professional medical advice tailored specifically for your situation rather than trying to self-diagnose or make assumptions based on general information alone.
