BFP 11DPO. Still horrified I’m going to miscarry again

My first pregnancy ended in miscarriage. 3 months later I found out I was pregnant with my now 19 month old. 3 months into his life I found out I was pregnant again, but miscarried again. I now just got a positive and I’m horrified I’m going to lose this one too. Any advice? I’m trying to remain calm and not stress out, but it’s super early. I know my body and I knew before it even showed on the test. Here’s today’s tests.
