Restless and worried 😥

Im a worried !!!
momma's please help 
This is my first (maybe second?) 
I had a chemical pregnancy back in January and I found out that I was pregnant a couple weeks ago, I'm 8 weeks now and my prenatal appointment is on Monday July 3rd and I'm sorta worried that I might be miscarring :( every time I wipe I get a little bit of blood :( and this mostly happens at night has any one else experienced the same?? Any advice would be greatÂ
