Thanks for your question on Healthcare Magic.
I can understand your concern.
Yes, we should definitely rule out
pregnancy first.
So get done urinary pregnancy test and
ultrasound examination of abdomen to rule out pregnancy.
If both these are normal then no need to worry for pregnancy.
Sometimes,
hormonal imbalance and
vaginal infection can also cause similar brown discharge. So consult gynecologist and get done clinical examination, hormone levels and microscopic examination of discharge.
You may need antibiotics.
Avoid moisture and perspiration in private parts. Keep proper hygiene of private part. Avoid
masturbation or sex for few days if you are sexually active.. Don't worry, you will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
