Your history suggests that you are experiencing gross hormone imbalance
and need further evaluation before a proper plan of management can be made. Your symptoms can mean a very early pregnancy
or hormone disturbance. In the current scenario, you should go for the estimation of the serum beta-hCG
titres followed by a trans-vaginal sonogram and if pregnancy is excluded, get a complete hormone profile. Please maintain a healthy weight, regular exercise and a healthy diet. Hope this helps.
