Unclear question: Was the blood test for HCG positive and urine test negative? If so, that is likely due to the blood test being more sensitive. The anomaly in wiping technique is not likely to be an issue.

The gums above my two front teeth are swollen and I need them to go back to normal within 72 hours what do I do?

Brush, rinse, floss: Brush and keep them clean, floss them gently and try rinsing with warm salt water in that area specifically. Rinse for a minute or so or as long as you can. This should help it go away. If the swelling is not going away you need to see your dentist to have it checked out. Good luck.

As required: But the more often you empty it likely you will result in smaller and smaller volumes. As your blotter volume diminishes the problem will likely increase.

Part of the team: Brain tumors are either benign or malignant and are either primary or due to tumors elsewhere in the body. Any patient with brain tumor needs a team support. There may be a surgeon, cancer specialist, neurologist, radiation specialist, chemotherapy team, rehab therapists, psychological support, etc. You can help by being part of the team. Alcohol in small amounts should not harm but no smoking.

Need Gynecology Eval: Vaginal bleeding is not always your menstrual peiod. Sometimes women get miscarriages that happen about the time that they expect their periods. Also, there are a lot of conditions that can develop in the uterus that can cause bleeding such as fibroids, uterine polyps, cancer, infections, etc. Your sister should go and see her pcp or a gynecologist for an evaluation of her vaginal bleeding.
