Threatened abortion !?

Danielaa💕✨ • Mother of a precious baby boy 👶🏽💙 In a relationship O5.12.13💏😘 •21♊️✨💁🏽•
Hello ladies so I went to my first doctors appointment Thursday since I've found out about me being pregnant . I found out last Sunday then took more test the days after ..so when I went to the doctors he did a vaginal ultrasound and he could barely see the baby like to me when I was looking at the screen I didn't see anything 😞😔 so he had me get some blood drawn that following Thursday and again today so I went in today and noticed the paper said threatened abortion what does that mean !? I'm trying not to freak out cause I looked it up on google and it says it could be a possible misscariage !!?? Anybody else experience this please please help me with some answers 😞
