Vaginal bleeding and 4 wks pregnant

Hi everyone I am 28 yrs old. This is my second child.. I found out I was pregnant Mon(4wks along) and started bleeding next day. At first it was spotting light pink and now it's medium flow and red.. Went to the ER Wednesday doctor diagnosed threatened miscarriage he told me I had a 50/50 chance. My HCG level was 95 went in Friday for quantitative blood work.. The wait is killing me, trying not to stress but wilh the holiday season it's hard to just take it easy.. Anyone else go through this?
