Could I Be Pregnant If My Period Is 12 Days Late?

Blighted ovum, which is also called the synonym "anembryonic pregnancy," is a situation where a fertilized egg is implanted in the uterus, but the embryo does not develop. I understand your worries about having two blighted ovums one after the other were scary. The most important thing is to consult your doctor, who knows the potential causes and comes up with the possible solutions that allow you to have a healthy pregnancy in the future. You could have further examinations which are done to help decide if there is an underlying factor that is causing this to happen multiple times. 

Multi-cystic means urine is filled inside the baby's kidney. These renal anomalies would start to show up around the fifth month of pregnancy. In most cases, this is not harmful to the baby and it can get cured on its own.

This indicates that both of your fallopian tubes are open and functioning properly. This is a positive result as it suggests that there are no blockages or obstructions in your fallopian tubes that could interfere with fertility or conception. It increases the chances of successful natural conception and may be reassuring if you are trying to conceive.

A negative pregnancy test means you're likely not pregnant. Stress can delay periods. Wait and test again in 1 week. If you're still concerned, see a doctor.

Pain in your vagina, after your boyfriend touched it with his finger, could be due to irritation or a small tear. The pre-ejaculate fluid he had on his hand doesn’t typically contain sperm but still can carry some risk of pregnancy or infection. It’s important to always practice safe behaviors and consider using protection to prevent any unwanted outcomes.

The  treatment depends on the cause of the urine leakage. I advise you to visit a urologist in person first. Based on some evaluations, the cause of the problem can be known and accordingly the doctor may decide whether your mother needs surgery or medications.
