Hi. I am 21 years old. I started my periods when I was about 15/16 and have always been heavy. At the moment I have been on them for just over 2 weeks I use the night towels all the time because am heavy and I have gone through 6 packets in the past 2 weeks. I have started feeling dizzy, sick and am always tired. Another thing is I constantly shake I have been like that for a while now I don t know if there connected. I have been to my doctors and to be honest she s useless she s gave me mefanomic acid tablets to slow the periods down but doesn t seem to be working as I am still really heavy and on my periods. X
