mid cycle bleeding

Hi, i'm 19. i had my first period this month sept 7, 2009 and it lasted through sept 13th. and then i started getting brown discharge on the 24th and then light bleeding the 25th up until now, its the 29th. i dont think this can be considered spotting cause there is flow. well my bf and i had sex on the 5th. we had used a condom and he said there semed to be nothing wrong with it after he cleaned himself up. so condom failure wasnt likely. however school just started and i have been really stressed out lately and the bleeding is only causing more stress. i dont know what to think. and i have been urinating more frequently but my liquid intake has increased since i havent eating as much due to the stress. please help =/

Your body is going through some hormonal changes, so, you can expect some different feelings and such during this time. I would definitely see a gynecologist however and have them check this out and give you a good female exam, it is good to rule anything serious out.
