Hello
Thanks for trusting us with your health concern.
When did you stop taking Krimson 35 ?
Normally are your periods regular ?
Why did you stop taking the Thyronorm, did you stop it on your own
Looking forward to hearing from you
Take care.

I do not remember the dates I stopped last month and took only for 3 days. I stopped Thyronorm by own . I started taking thyronorm from two weeks and Dr. is giving thyronorm for my regular period.i.e i used to get my period 1 month 5 days. to get my periods to exact date dr. gave me Thyronorm. We are planning to have baby and 6month back my TSH was 3.08 so prescribed for Thyronorm till i get pregnant.

Detailed Answer:
Thyronorm is not a medicine to be used to regulate your periods.
You have to continue taking Thyronorm till your doctor tells you.
Stopping medication in this manner on your own will lead to many complications.
Please take a pregnancy test tomorrow morning and let me know the result.
Take care.

Hi Dr. XXXXXXX

There is no chance of me getting pregnant as my husband is in Onsite from past 3 months. Do you need any other info.I wanted to know why my period is getting delayed?

Detailed Answer:
Normally do you have regular periods ?
If you have irregular periods as a rule, then there are various causes for this.
Thyroid hormone imbalance maybe the cause, as you stopped taking the medication on your own.
Stress, anxiety, late nights, smoking, drinking, weight changes, exercise, diet changes - all of these can cause your period to get irregular.
You should consult a gynecologist and go for a pelvic sonography ( ultrasound ).
ALso hormone tests - FSH, LH, TSH, Prolactin, OGTT, DHEAS, Free testosterone, Lipid profile.
That will reveal the reason for irregular periods.
Take care.
