is this normal?

Hi everyone! I am 15 years old and i started my birth control pill in the middle of may.

I haven’t had a problem until a couple of days ago when i decided to skip the seven day break and just start a new pack of active pills.

Keep in mind i usually take the pill within a 3 hour window of the time i started it. (i know i’m really trying to take it on time is just very forgetful!)

I’m taking active pills however i’m having really bad bleeding, is it my “period” or am i just having bad breakthrough bleeding/ spotting.

It’s getting to the point where it is really crampy both in my back and stomach area. I volunteer at a children’s summer camp and this is really hindering my work performance.

Should i talk to my doctor or is this normal?
