My period will not stop because of birth control?

i was on seasonique for about a month, and one day i accidentally forgot to take my pill, so i did as i was told and took 2 at the regular time the next day. That day, i started my period and was on it for 5 weeks straight! At that point, i was extremely fed up and decided to stop taking it all together. My period continued for about 3-4 days after i stopped taking the pills. I waited for about a month and a half and decided i needed to get back on birth control. So i went to the clinic and they gave me a prescription of a different type of birth control pills. The day after i took the first pill, my period started again. It's been going for 2 weeks straight now and this is really pissing me off!! I haven't forgot to take any pills, i've been taking them at the right time each day, i'm not sick, i'm not on any other medication, i'm a healthy 17 year old. I don't know what to do at this point. The clinic isn't open on weekends and i don't have good insurance, so i don't want to go to the doctor because then i would have to pay for an expensive consultation. Does anybody have any advice as to what i should do? I'm thinking about stopping birth control all together again, because all i want right now is for my period to stop.
