Thanks for the query.
Alteration in the menstrual cycles and in menstrual flow can occur due to many causes. Hormonal
imbalance, thyroid abnormalities, change in hemoglobin
levels, stress and strain, weight changes etc multiple factors can influence the menstrual cycles.
So possibly this spotting can turn into menstrual flow.
If you are having doubt regarding pregnancy
, once go for blood test
If the test comes negative, the spotting could be starting of menstrual flow.
And in the next cycle, you can try for the pregnancy.
If the test comes positive, once consult gynecologist and get examined to rule out impending miscarriage
or ectopic pregnancy.
