I missed a period and got light flow of brown discharge for 3 weeks instead then second now the is white or yellow has an odd smell could it be pregnancy infection?

It's important to see a doctor to determine the cause of your symptoms and get the appropriate treatment.

Brown discharge is often a sign of old blood, and it can be normal to have light brown discharge for a few days before or after your period. However, if you've missed a period and are experiencing brown discharge for 3 weeks, it's important to see a doctor to rule out any underlying medical conditions.

White or yellow discharge with an odd smell can be a sign of an infection, such as bacterial vaginosis or a sexually transmitted infection (STI). It's important to see a doctor to get tested for any potential infections and receive the appropriate treatment.

In the meantime, here are some things you can do to help manage your symptoms:

* Practice good hygiene. Wash your vulva and vagina with warm water and mild soap every day. Avoid using harsh soaps or douches, as these can irritate your vagina and make symptoms worse.

* Wear cotton underwear. Cotton underwear allows air to circulate and helps to keep your vagina dry. Avoid wearing tight-fitting underwear, as this can trap heat and moisture and create an environment that encourages bacteria to grow.

* Change your panty liner or pad frequently. If you're experiencing discharge, change your panty liner or pad every few hours to prevent bacteria from building up.

* Avoid sex. If you're experiencing discharge, it's best to avoid sex until you've seen a doctor and gotten a diagnosis. This can help to prevent the spread of infection.

Remember, it's important to see a doctor if you're experiencing any unusual symptoms, such as missed periods, brown discharge, or white or yellow discharge with an odd smell. These symptoms could be a sign of an underlying medical condition, and it's important to get the appropriate diagnosis and treatment.
