Hello and welcome to Ask A Doctor services. I have read your query and here is my advise. * The cough is seemingly related to lower respiratory tract infection via some sort of bacteria or virus. * The abdomen pain and vomiting are in concern with excess straining at abs secondary to excess cough reflex. * The vaginal bleed though spotting sound underlying hormone imbalance due to infection with pyrexia condition. If you can provide all details of your reports of lab data, x-ray, ultrasound and rest of the things, I can focus further regarding the same at a better pace. Thank you. Regards.
