STOP using tampons immediately and go see a lung specialist. I have been having the same problem for years and finally connected the two. I went to the E.R. Many, many times only to have them tell me I was fine. I have been hospitalized for "ulcers", "blood clots", and "bronchitis" more times than I could count! Finally I decided to see a lung specialist and made an appointment. I told him that I cough up blood but ONLY during my period and that I thought it could be a rare form of endometriosis. He pretty much told me it was too rare and that I couldn't possibly have it! What an ass! But he did give me a pamphlet about endometriosis and some of the things to avoid were, tampons and intercourse during your period. The next period I used pads instead and the difference was AMAZING! I still would cough up blood but a very VERY small ammount! If I had been using pads all along I would have never of noticed it. I made another appointment with a different specialist and pretty much told him "This is what I have now what are we going to do about it?" He diagnosed me with Catamanial Hemoptysis right away. He says it's VERY rare but treatable. I have never been so relieved after 5 years of being told it was "nothing" I hope this helped.
Vomiting blood during periods is one of the signs of pre menstrual syndrome. Other signs include breast tenderness, fever, fatigue, dizziness, edema, body aches, cankers, headaches and emotional disorders. Changes in diet and aerobic exercise can help you. Don't take any NSAID pain killers. Nutritional supplement like Vitamin B6, calcium, magnesium are also recommended. You should discuss this with your doctor.
You need to go see the doctor immediately I've never heard of that.
It is Parenchymal endometriosis. You need to see a gyno who has actually heard of them because most of them have not. I have this disease.
Honestly this problem is a new one for me. Please see your Doctor. This coughing up blood may not be directly related to your periods. Blood from the lowere torso which has its own enclosed passageway should have no effect on what comes via your mouth. When this occurs again visit your Doctor as it is happening. He will probably want a chest x ray and complete blood count. Anytime you see blood from the mouth and you don't have a nose bleed or bleeding gums, take that red flag to the Doctor quick!
