Hello everyone , I really could use some help . I've had a history of miscarriages & a week ago we found out we're pregnant . On 6/11/15 when I was seen at hospital I was told I was pregnant they ran my hcg levels and they were only a 20 . They wanted to me have retesting done , which I had done on Saturday 6/13/15 and I was a 68 . I experienced light pink almost brown spotting only lasted a day . Could that be implantation spotting ?? What im not understanding they said they detected pregnancy in urine and blood or course . I was also seen on Monday 6/15/15 and was 156 . I'm confused on how far along I should be ?? My LMP was 5/15/15 .. But their saying im early ?? I'm so confused and worrying due to having miscarriages !! Everything seem normal ???
