13 weeks and getting scared

So i havent seen my little one yet, well i have but that was at 4 weeks for dating. Ive had multiple miscarrages and this is my first one to make it this far. Well, im getting scared that something may have happened and we dont know about it. I have an appointment at 14 weeks 4 days, so 11 days away, but i want to see/hear him now... anyone else have to wait so long to see there little one?
