welcome to health care magic
i suggest u to go for pregnancy
test kit at home as it is common to get brown discharge during early pregnancy obviously first thought is often that something is wrong however this is not always the case.
brown discharge may be the indication of miscarriage
but only if you have itching redness
,pain in abdomen and genitals.
more common reason for brown discharge is that body get rid of older blood remains.
it is always best to err on the side of caution if you expierence any discharge throughtout the pregnancy.
but in your case you first need to get confirm through urine pregnancy test and physical examination is needed so consult gynaecologist if pregnancy test is positive.
