Hormone imbalance doubted. Condition!

Since April my menstrual cycle is not good it's like 30,27,28,30 days  and for this month it's came after 34 days. I had been observing mood swings, getting irritated easily and for long time I had no desire of having sex(10 months). hair at chin is growing thicker than before and hairfall also. I am worrying about this condition. even though I was sleeping for 8 hours I am feeling very tired. getting stomach ache and vomiting during 5 days of periods. and I observed getting head ache for last 20 days daily in the evening. I consulted a doctor in April and she had recommended to take codesoft EPO capsules for 3 month I had took them. at that time of taking that medicine I observed 27 and 28 days of menstrual cycle and I used to get overheating during this period also. is there any emergency of consulting doctor, is there any problem in future if I neglect now. i taught it would be imbalance in hormones. what I should do now to get out of this condition
