I have headache once in three weeks and i don't get my periods, and after eating the washing powder i didn't drink water or eat anything till evening. So can u tell me what should i do?

Ideally, you would be required to call for healthcare assistance on an urgent basis, but as you did this years ago and experienced no symptoms, thus it does not seem to me that you have anything to worry about. However, what's to consider here is, that the substance which you consumed can render your internal organs burned or damaged, so if you didn't experience pain but is possibly having some health problem which is growing and has continued to sustain undetected, then in that case you may want to contact a healthcare professional, and our page can help you with that regards - General Physicians in India.
