Sorry for the image !
yes it looks like a yeast infection. Does it itch and does the discharge smell fishy or sweet ?
Yes, it looks like a yeast infection
It itches sometimes and yesterday I got a brownish discharge
are you spotting, is your period coming ? Brownish discharge generally means you have blood mixed with discharge. No blood in your discharge will be clear opaque(healthy) white thick or runny discharge usually YI and if it starts to go yellow greenish with foul smell is usually BV. Of course everyone is different and thats why you get tested. Does your vagina have any sores or white bumps ? any open sores on your vulva ?
