Hi.. Thanks for query inHCM, As you told 1 week ago you got your periods,& you did pregnancy test yesterday x2 tests --ve means you are not pregnant, when you miss your period then do pregnancy test,now no need to do.You have pain abdomen-stomach before period coming ,it is known as Premenstrual syndrome (PMS)-- It is physical and emotional symptoms that occur in the one to two weeks before a woman s period. Symptoms often vary between women and resolve around the start of bleeding. Common symptoms include acne, tender breasts, bloating, feeling tired, irritability, and mood changes.Some women(3-8%) get PMS which require no treatment,no need to worry, ,only panadol tab or ibuprofen tab(after food) can be taken if pain -make sure u do not have peptic/stomach ulcer .follow healthy life style; drinking plenty of fluids to ease abdominal bloating eating a balanced diet to improve your overall health and energy level, which means eating plenty of fruits and vegetables and reducing your intake of sugar, salt, caffeine, and alcohol taking supplements, such as folic acid, vitamin B-6, calcium, and magnesium to reduce cramps and mood swings sleeping at least 8 hours per night to reduce fatigue exercising to decrease bloating and improve your mental health reducing stress, such as through exercising and reading going to cognitive behavioral therapy. I hope you got the answer Regards, Dr Md.Ibrar
