Bleed in pregnancy

Kym
Has any one experienced any bleeding during their pregnancy? This is my 5th pregnancy and I've done nothing but bleed! It's so freaky I lost a lot of blood on Wednesday night and Thursday so I obviously thought I lost my baby but nope he is doing great, (I'm calling baby a boy as I've had 4 boys already) 😂 
apparently it's really common to bleed so was wondering if any one else has been through the same and if so how did you cope? Did you bleed right though till the end? I'm almost 12 weeks but can't stop worrying
