Hello, I'm 25 yrs. old and I am almost a month late with my period. My last period was on Nov. 28, it is now Jan. 20. Instead of a period in Dec. I had light brown discharge for about three days (It was never enough to use a liner or anything). I have taken 4 home preg. test, they were negative. I went to Planned Parenthood for a blood test 3 days ago and it was negative as well. I have never been this late before and I have never experienced brown discharge instead of a period before. I am having cramps like my period is going to start but nothing comes. My breast are sore (especially on the sides) and feel swollen. I'm experiencing some tiredness at times, It feels like my body is tired from working out but I haven't been. I read that these are some pregnancy symptoms but I'm getting negative results. Courios on why my period is so late.

Since the blood test has come out negative, chances of pregnancy are less. From your symptoms it looks like an irregularity in periods. High levels of stress, cholesterol, hormonal imbalances, chain smoking and dramatic changes in your lifestyle may be common causes of your irregular periods.

Other causes include medical conditions like PCOS and fibroid uterus. PCOS is diagnosed by blood tests like blood insulin levels, serum testosterone and androgen levels and ultrasounds. Fibroids are benign tumors of the uterus. They are diagnosed by an ultrasound of the lower abdomen or a CT of the abdomen.

If this was the first episode of irregularity in the periods, then wait for the coming cycle and try lifestyle modification by reducing stress and decreasing cholesterol levels. But if the repeat happens, then please consult a gynecologist and get yourself thoroughly examined to diagnose the cause of irregular periods and start with the treatment.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For an exact diagnosis, you are advised to consult your doctor. I sincerely hope that helps. Take care.
