Hi there
Here is some info for you -
The first thing you must know is that implantation bleeding is a normal phenomenon for the female organism and the first symptom, indicating that you are definitely pregnant. From now on your body is going to launch a global hormonal rearrangement. Spotting during implantation doesn’t have any impact on pregnancy itself. It rather gives you a personal privilege to determine your pregnancy even earlier than a hCG-test can do this.
The problem is that women often take pathological vaginal discharge with blood for implantation bleeding. You must be alarmed if your discharge is accompanied by strong lower abdominal pain, severe nausea, sudden vomiting and dizziness. These can be the symptoms of ectopic pregnancy or miscarriage. Such conditions require urgent medical help.
My suggestion - better visit a doctor and get a clinical pregnancy test done and a detailed checkup. Do not forget to mention all of your symptoms. Good luck
