Scared

Have anybody had an issue with their placenta? Went to my appointment today and my doctor looked over my 20 week scan and said there might be an issue with my placenta and referred me to an high risk doctor. She didn’t give me much information, but she ordered blood work. My next appointment is Thursday and that’s when they will be able to tell me more information. The baby is healthy and had a strong heart beat , this is my first pregnancy and I’m scared. Also my blood pressure has been high and having a lot of headaches.
