14 weeks and bleeding

Hi Everyone. I am about 14 weeks pregnant with my third child. This pregnancy is completely different from my other 2. I have had light spotting throughout and yesterday was at ER bc I had heavy bleeding when I went to bathroom, but no pain. They did every appropriate test in ER and baby is fine. They told me to rest and follow up with my OB. I am a nervous wreck and don't know what to think. We have 2 girls and this pregnancy is annoy. Looking for some comments on anyone else who has had this experience. Thank you.
