hi, I'm 23, I'm on the pill, long term partner, and this week I should have had a period lasting 4-5 days. Instead I only had a bare 3 days very weak period. Could this be because I was ill and had an infected throut and was taking homeopatics this week? (It was quick and sudden).... I'm just scared, I did not miss a pill, my my periods have never been this short!
