cramping, sore nipples, heartburn, no periods, sluggish, dull, low appetite.

Mine is a 39 day cycle but always on time. last month it got delayed by 10 days. THis month i havent yet got it. its late by 15 days. I was nausic for the past few weeks and threw up once or twice. recently have and sore adn too sensitive nipples. get heart burn in the nights and find myself having low appetite in the morning-normally my appetite is good in the mornings but now the appetite is too much towards evenings. Feel mentally inactive for my otherwise sharpness, absentminded, sluggish and oversleepy in the mornings. Emotions fluctuate as well. 5-6 days back i had stained my napkin with slight cramps, I thought my periods was on but it did not continue. sometimes i get whitish discharge. my facial skin has broken into few acne, i have had heavy acne as a teenager. I am 29 now. HPTs show negative. Start intercourse first ever in my life from teh month of September, had fears of intercourse previously. Sexual life is normal and active and fulfilling. had hyperprolactinimia last March, April was corrected with cabergoline minimal dosage. My gynecologist attributed it to domestic and professional stress. Scan and other tests showed a normal uterus with a good endometrium. No family history of infertility. Mother had 4 babies including me. I need help.
