Patient: Hi, my last period lasted for more than a week, which is abnormal for me because it’s usually about 5 days tops. Tehreafter, I had clear discharge which I usually get, but about 3 days ago, it turned white with a fishy smell. Last night, I felt like I had to go to the bathroom every 30 seconds, like a uti infection ( which I’ve had before). This morning, when I woke up, I found blood on my underwear and it’s been discharging brownish liquid ever since. May I know what I can get for this? Prefably over the counter if possible. Thanks!

Doctor:
