Could the amount of liquids I drank before taking this last test affected my results?

Here is a list of what I have experienced:

-1 week before my period was due I had cramps and felt a bit bloated for a few days and my breasts were extremely sensitive and hurt a lot

-4 days before my period was due I took Plan B after the condom broke (but no ejaculation)

-1 day before period was due I had light brown and pink spotting

-No more breast tenderness or pain at all

-The day my period was supposed to be due I had a big gush of the darkish red blood I usually get with my period. But after that it was just light brown/red bleeding for about 6 days (my normal period length)

-I took a clear blue easy digital pregnancy test in the middle of this light bleeding and it was negative

-Symptoms during/after light bleeding: waking up around 1 a.m. every night sweating, some headaches, tingly hands and feet, sore throat

-9 days after start of light bleeding I took a first response pregnancy test and there was a VERY faint positive line. Later that night my abdomen had great pain when I would push on it hard (I had been taking vitamin c pills every two hours all day- maybe why it hurt?) Also that night I had lower back pain near my tailbone right before I went to bed

**I drank 2 diet cokes throughout the day and a medium coke at a movie at around 7 o'clock that night too

-10 days after light bleeding started I woke up at 1 a.m. sweating and dosed on and off until 3:30 a.m. when I decided to take a clear blue easy digital response test that came out negative

Could the amount of liquids I drank before taking this last test affected my results??????

Please help!!!!!!!
