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.

Pain in your vagina, after your boyfriend touched it with his finger, could be due to irritation or a small tear.

Variant reasons can come up with missing menstruation, like stress, fluctuations in weight, or hormonal deficiencies that cause it. If you haven't had your period, try to watch for other symptoms that may have come along with it, such as headaches or mood swings. If you worry, it's better to go and talk to someone you feel secure with, such as a parent or school nurse, who can then show you what to do to be of better help to yourself.
