Hi, I am 37 years of age. My periods are late by 15 days. I think I am expecting for the first time but scared to take a test because of it comes negative I will be disappointed. I can feel pain at times in my lower abdomen the way it happens before period and my breasts are also sore. I read somewhere that these symptoms also prevail if you r pregnant. I feel little nauseated and fatigue. Pls suggest.
