I am 20 yeards old. I had brown spotting for about 4 days. It was a week before I got my period. I had been on medicine for a sinus infection. One was a steriod pill that was taken for a month and then after that month I was put on sulfameth. Once it was time for my period to come I got the really bad cramps I usually get and heavy bleeding for 2 days and then light bleeding for about a day and a half. Is this normal?
