Possibly pregnant and terrified after two miscarriages

My husband and I have had two miscarriages in the last 14 months. I took a pregnancy test on a whim yesterday at 9 DPO and had a very definite positive. I’m going to the doctor tomorrow to get some tests done and a blood pregnancy test and I am so. Scared. I can’t stop thinking about if something happens and obsessing over the cramps I have been having for the last 6 days. Did you ever get over this fear? Do you have any positive stories to share? Im so so worried and terrified and a little bit hopeful.
