First trimester, Bleeding during pregnancy

Shannon

Hi guys I’m 5 weeks pregnant and I was bleeding so heavy today like gushing out blood and I thought it was a miscarriage I went to the ER they did a ultrasound and blood work , they said the pregnancy is in the right place and that my blood levels are matching up , they put my on pelvic rest , has this ever happened to anyone and they still had a healthy pregnancy, p.s I have no pain
