I had a 5 day period it's been 9days and now i'm spotting is that normal or should i see a doctor or take a pregnancy test?

Maybe; Yes do test: Even teens using a most effective contraceptive like an IUD or subdermal implant,would benefit from a blood betaHCG test ASAP to be safe and if positive, need a Gyn evaluation and pelvic sonogram. If your pregnancy test is negative and you health otherwise good, chances are your cycles will return spontaneously to normal in 2 to 3 months. If they do not or worsen, get a Gyn consult and life plan.
