Good day all,

Last month (Month) I had one of the worst periods ever, I was in pain for a full four days, heavy flow and threw up everyday I eventually went to the Dr and got two injections for the pain and medication for the nausea. I was put on bed rest (missed a day of work), I went a contraceptive Yasmin. Well not this month in April my periods are over a week early, not as painful and the flow not bad. Is this normal or should I worry?
