My sister recently stared bleeding after sex, just a little pinkish blood. she has a couple of early pregnancy symptoms such as fatigue, increased appetite, heartburn coming out of the blue, and she missed her period. What worries me though is my sister has had several health issues. She's prone to kidney stones and has had bad ovarian cysts to the point that he doctors had been discussing giving her a hysterectomy when she was only 15/16 years old (they ended up being able to avoid it by putting her on birth control for a while). Right now she's putting off getting a test to see if she's pregnant or going to the doctor to make sure that it's nothing more serious because she's embarrassed. Should we be worried?
