I found out Thursday I am pregnant. Urine test at the doctors office came back negative blood work came back positive with a hcg level of 43. I have had two miscarriages and I am so scared. My first miscarriage was a year ago at 10 weeks my last miscarriage was this past August at 5 weeks. I was so surprised to get pregnant again right away considering it took me a year to finally concieve again and sadly ending in another miscarriage. I go tomorrow to have more blood work but this is driving me crazy. I'm assuming I should be around 4 and half weeks pregnant. Is 43 an okay number or should I be worried about another  miscarriage?
