Miscarriage, I get it now

I went to the ER Wednesday for spotting and they put me on bed rest for threatened miscarriage. HCg was at 130.7. My pregnancy tests are still positive and I had a drs appointment this morning. Uterus measured at 5/6 weeks so was normal. Still just little spotting not even enough to leak into my undies while I slept. He said he wasn’t comfortable making a diagnosis without further labs bc I’m positive on the urine and my uterus is measuring 5-6 weeks. He said he’s seen some women who bleed so badly he thought they were hemorrhaging but they had perfectly healthy babies and he’s seen women miscarry with little to no symptoms. He did tell me that we were most likely dealing with an ectopic pregnancy, implantation bleeding or early miscarriage but the fact that I have a healthy history of a pregnancy that went passed full term and healthy vaginal delivery and being pregnant now told him that my body can carry a baby with healthy results, we are ovulating, my tubes are open and his sperm are also healthy enough to get to and fertilize my egg. We’re young and healthy. He said it just happens sometimes that he and his wife experienced a MC and they went on to have a healthy child. He promised me with those factors considered if it resulted in miscarriage he would see us through bringing home a healthy baby. I have more lab tests Monday and an ultrasound the 18th that he said he wanted both regardless of lab results, to set the way for us having a healthy pregnancy. At around 5 this afternoon I read my lab results from this morning and my hCg is at 99.7 😭 immediately after I started bleeding horribly. We are heartbroken. My bf is shattered and has cried as hard as me. But wants to try as soon as possible. I just wanted to share my story because you ladies always understand and I feel so alone. He’s so supportive but he’s so broken and I’m bleeding so badly and just want so desperately for it to stop and go back to when my baby was fine. 😭
