Thanks for the query.
Missed periods can occur due to many causes.
The possible causes for your problem are :
imbalance due to causes like ploy cystic ovary disease, stress and strain, weight changes etc.
- Abnormality in prolactin
- General conditions like anemia
So you once consult gynecologist, get examined and go for investigations like:
-Thyroid hormonal profile
-Prolactin levels estimation
and blood sugar levels estimation.
By this workup the possible cause for your problem can be identified and treated.
Breast tenderness can be seen due to hormonal imbalance, impending periods, during ovulation and to abnormality in prolactin levels.
By investigations the possible cause can be identified.
