Hi Mitul,
Thanks for writing in.
Sometimes periods can get delayed if you are stressed , anxious etc. I would advise you to wait for a week and repeat the urine
pregnancy test. If it is still negative, you could do a
serum Beta hCG test to check for pregnancy.
It is also possible that your present brown discharge with cramps and leg pain , might be the onset of your periods.
However, In the presence of severe bleeding per vagina or severe lower
abdominal pain, please visit your gynaecologist .
Hope this helps.
Regards,
Dr. Divya Kuttikrishnan
