Hi,
Welcome to the forum.
You are spotting with brown discharge due to low
haemoglobin % in your blood. When there is a deficiency of red blood cells, the uterine endometrium may not be able to form or shed normally. Scanty
menstruation is the commonest cause of low Hb% in blood.
Fatige,
tiredness are symptoms of weakness. Take nutritious diet rich in iron, calcium, protein, nuts, fruits, berries along with appropriate quantity of
carbohydrate. Keep well hydrated and take energy drinks. Avoid smoking, alcohol, caffeine or any other addiction.
Nausea, vomiting, mood swings, headache, abdominal pains are some common side effects of birth control pills.
Continue to take iron and
vitamin B12 tabs that your treating doctor has prescribed. Take adequate sleep. You will start getting normal menstruation when your Hb% improves and your general health gets better. Take care.
