Blighted ovum symptoms may be few and far between, if you get any symptoms at all and can be totally normal symptoms of pregnancy. The majority of people who suffer with a blighted ovum do not realise that anything is wrong at all until they have an ultrasound. Your body was producing pregnancy hormones and you were for all intents and purposes carrying the start of a new life.

The truth is that it is very difficult, if not impossible, to tell if you have a blighted ovum just by your symptoms and really the only way to know for sure is by having the ultrasound scan done so that they can look at your uterus and determine if there is an embryo present or not or just the gestational sac. Because the body will still think that you are pregnant, it is entirely possible that you will get through your first trimester without knowing that you have a blighted ovum.

Obviously this can be very distressing to get to 12 weeks when you think you are over the worst part and find that the embryo never developed. This is only going to happen though in places where the first scan that you get is not until the 12 weeks mark like in the UK if you do not have a history of pregnancy problems. The majority of blighted ovum pregnancies are diagnosed much earlier than 12 weeks however, so it is highly unlikely that you will get as far as 12 weeks and then be diagnosed.
