Hello tisha ;
welcome to HealthcareMagic
The first sign of pregnancy
is a missed periods then the other signs follow like nausea
vomiting;dizziness;breast tenderness etc so you have to see if you had any of these.To confirm you can do a repeat pregnancy test and if both lines are clear then you are pregnant.The spotting can be due to hormonal
imbalance or even due to pregnancy if you have threatened abortion
.I would suggest you to repeat the pregnancy test at a aboratory and then consult a Gynaecologist for examination and further treatment.
