Probably: It is time to see your dentist who will either treat this or send your to a special dentist to treat called a Periodontist.

Gingivitis for sure: Periodontitis is a chronic inflammation or infection of the tissue around the teeth and sockets and sometimes the jaw bone itself. Your description is consistent with gingivitis. This can arise from poor dental health or even from a vitamin deficiency or side effect of certain medications. See your dentist as soon as possible. It could lead to periodontitis so prompt treatment is important.

Periodontitis: Yes you could have periodontitis affecting the bone laying under the soft tissue. Puffy, swollen and loose gums are some of the signs of gingivitis due to poor oral health, some predispositions and other factors. Gingivitis is the first stage of a more dangerous condition known as periodontitis. It is possible that you have gingivitis or both. Must see a dentist ASAP to avoid tooth loss

Possibly...: But without a visualization, radiographs, and probing depths, impossible to tell. Make an appointment with a local dentist to be evaluated.

Also consider diet: Definitely see your dentist. They may even refer you to a periodontist (gum specialist) for further evaluation, depending on your status and history. Diet can play a big role in oral health. Are you getting enough vitamin C? Low C, along with low B's & D, and other nutrients, can contribute to gum issues.

Not yet: You defiantly have severe gingivitis which can go into periodontitis, tho you are awfully young for that. If you can not afford to have your teeth professionally cleaned, sit in front of a mirror and floss your teeth. Try of see where exactly the blood is coming from and floss the heck out of those areas. Set a timer for two minutes and brush for that long.

Probably: Periodontal disease is both chronic and progressive, so don't put off treatment. With the symptoms you have reported it would be best to see a specialist Periodontist for evaluation and treatment of gum/bone damage.
