Starting cramping last night with some brown spotting.. woke up this morning to full on bleeding and cramping. Went to the ER and they did an US, said everything looked normal but they didn't pick up a HB (I'm 6 weeks 3 days) My hcg lvl was only 2500. They basically sent me home on bed rest and said I might miscarry. My first OB app was for this coming Tuesday. . I'm so scared that I'm losing my baby.. How do I cope with this?
