In molar pregnancy, a tissue that should normally grow into a fetus develops abnormally in the uterus instead, triggering normal symptoms of pregnancy.

Vasa Previa

This is an extremely rare condition, where the unborn baby’s blood vessels can tear, thus depriving the baby from oxygen and making it bleed profusely.

As stated earlier, bleeding during the first trimester may not indicate any serious problem. At this stage, for handling bleeding, you can opt for pads that will help you to track the color of blood and the amount of bleeding. Also, if you are bleeding, it is better to avoid sexual intercourse for the time being. In case the bleeding is excessive, getting in touch with a doctor can be a good idea.
