This is my first month on this pill, and i started my period two ...

I started this pill 6 days ago, on the first day of my period, started it to help with PMDD symptoms, but over the last 6 days, I have gained about 7 pounds, even though I have been running about 30 miles over the last 5 days...cant seem to get enough food, feel tired and sluggish and VERY HEAVY, and I just feel like crap...I have an appointment with my Gyn in 8 days, but at this rate, I dont want to feel like this any more and gain more weight (I am a fitness professional and my livelihood depends on me not being overweight and I am already past the threshold!) I literally look like I am pregnant...bloated in the middle and breasts are huge!

anyone know how stopping this pill suddenly after a week will affect me? Has anyone else had these issues?

i am 17 years old. i am on day 17 of this pill on my first cycle and i have had my period for 7 days. at first i thought it was just spotting but over the past week its been light to heavy bleeding. I have had mood swings mainly this week but they could have been caused by the fact that im a little pissy that i am bleeding so much when i shouldnt be. Since ive started taking the pill ive lost 5 pounds (but ive also started daily 2 1/2 hour practices for my sport shortly after day 1). I am so stressed out that i wont stop bleeding. ive always had regular periods. i cant tell my parents b/c i got the pill from a free clinic, and i dont want to call the clinic b/c i don't have time to go all the way down there.....should i be worried?? my friend who started the pill the same day as me has not experienced anything like this, she thinks its just my uterus wall lining thinning out but i dont know.... please help..
