US dating: Ultrasound is one way to date your pregnancy, but it is not going to be good enough to determine paternity based on the time of intercourse. You will have to wait for a genetic paternity test after the baby is born.

Lots of self care: It is critical to continue to take care of yourself when you are the caretaker for others. Make sure you have good sleep habits, good eating and exercise routines, and continue to be involved with others socially. Caretakers are at greater risk of developing health problems as a result of increased stress. Monitor your stress levels and seek the support of others to maintain your mental health.

Depends: If a patient has had surgery, they will most generally form adhesions. This is very true for women who've had cesarean delivery. If the goal is pain reduction, it may be worth have laparoscopy, but if just curious, may not be worth the risk involved having surgery.

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.
