hi i have suddenly begun to experience bleeding just before ovulation , it is heavey, clotted and painful. I also have pain in lower abdomin a lot and lower back. I have also had difficulty eating for the last two or so months i feel like the food is stuck or that i am going to be sick when i swollow it. I have also had quite bad headaches for the past three weeks on and off and felt very tired. I do have slightly low iron levels but have been taking iron and i know i m not pregnant. I havent changed my diet or exercise regime and am about 3 stone overweight .
