Hello dear,
I understand your concern.
In my opinion the
irregular periods could be due to various reasons like stress,PCOD,
overweight,obesity,
hyperprolactinaemia where in there is increased serum prolactin.
The normal cycle duration varies between 21-35 days in different women.
Anything more than this regularly should be evaluated for the above causes by necessary investigations like
ultrasound,thyroid profile,serum prolactin etc.
As you have spotting along with cramps the
pregnancy is to be ruled out.
As the pregnancy test is negative I suggest you to repeat the test after a week.
Because usually the pregnancy test gives accurate results a week after missed period.
If the pregnancy test is negative the pregnancy is ruled out and the spotting might be due to hormonal imbalance and the above causes should be ruled out.
Nothing to worry.All the above said causes are treatable.
Adapt healthy lifestyle like exercise daily and healthy nutritional diet.
Weight reduction in case of overweight or obese also helps in regularisation of cycles.
Hope this helps.
Best regards...Dr.Srilatha
