Third time mama

Deborah • I am a mother of two of the most handsome boys , wife to an amazing husband
Hi everyone I am a 29 year old mom of two boys 2 and 4! This is my third pregnancy and right now I am 6 weeks and 3 days! Yesterday I started bleeding red blood and cramping , I went to er and they said I was still pregnant that I need to do a repeat blood test this morning ! I am scared and very stressed! Both my previous boys my first was premature second was emergency c-section however I never experienced bleeding with either one! Is this normal ? Has anyone else ever bled with there child this early on?
