Help!!

Kristin
I found out I was pregnant about 11 or 12 dpo. I got faint lines on positives. Got a blood test 12 dpo. Nurse said I have hcg in my system but the levels are low and they are measuring out for me to be 1-2 weeks pregnant so they wanted me to come back a week later. A couple days after that I took a digital test and it said pregnant 1-2. Every day I've been testing and continue to get positives. Today I went back for a blood test again & the nurse said my levels went up a little bit but not much and they still can't consider it positive so she wants me back in Two more weeks. Then she told me if I start bleeding or cramping to come to the ER immediately. Which I know what that means.. I've had a miscarriage in the past. We have been trying so hard for this baby 😔 Anyone experience this and have a good outcome?? Or anyone currently experiencing this??
