My gynac prescribed iron tablets from the second trimester and the dose depended on my hemoglobin level. She said dont self decide the amount, it varies per person. She also told me to take it with vitamin C and avoid tea or milk around the same time for better absorption.
My iron dropped quite low and I needed a higher dose under close watch, so please dont guess the quantity yourself. Get your hemoglobin tested and let the doctor decide. Too much or too little both arent good.
Along with the tablet my gynac prescribed, my amma made sure I ate dates, jaggery and greens for natural iron. The combination really helped my levels. But always go by the dose your doctor sets, dont increase on your own.
