Hi, for the past few years since I started my period which was at age 14, i have always had a cycle of 28 days, never late but always heavy. In the past few months my period pain has incresed and I have alot of blood clots, each month seems to get worse, and my cycle has 27 days or 26 or 25 days, varys each month. For the past 4 months it stayed on 26 days, but this month I started 4 days earlier then the 26 day, so my cycle has changed again!! I don't know what could be the reason, we have been trying for the past year and 5 months.. but nothing as yet! could you give me any suggestions to what to do etc.. Many thanks
