The symptoms you are describing could indicate a miscarriage, but it is important to see a doctor for an accurate diagnosis. Some of the symptoms you have mentioned, such as heavy bleeding, blood clots, and yellow-white sticky discharge, can be signs of a miscarriage. Additionally, the light spotting you experienced last month could have been a sign of implantation bleeding, which occurs when the fertilized egg attaches to the lining of the uterus.

It's important to seek medical attention if you're experiencing these symptoms, as a miscarriage can sometimes lead to complications. Your doctor will be able to perform a physical examination, order appropriate tests, and provide the necessary treatment. They can also provide support and guidance during this difficult time.
