Ttc after miscarriage in October

I was pregnant with my third baby. I found out my progesterone was low at 5 weeks along so was put on progesterone. The same happened in my daughter’s pregnancy and I carried her to term and she was born healthy, so I tried to hope for the best and not worry. We saw a heart beat at 8 week ultrasound, which made me breathe a huge sigh of relief. Doctor said everything looked healthy so far, strong heartbeat and size was dating almost right on track. I was so tired and so sick this pregnancy and suddenly about 10 weeks along I felt fine. I was relieved but then started seeing light bleeding around 11 weeks. The nurse I talked to reassured me it could be normal and then bleeding stopped. At 12 weeks 4 days I felt crampy and the bleeding started lightly again. I decided to go to the ER since the nurse told me it could be fine again and to just wait for my appointment that was a week away. The Er did an ultrasound to find baby had no heartbeat. I ended up miscarrying at home the next day, hemorrhaging and then being readmitted over night to the hospital. I did not need a blood transfusion, but I lost a lot of blood. I was crushed and still am, but my husband and I feel ready to ttc again.

I am terrified though, and I am wondering how you cope with anxiety throughout the next pregnancy after a loss. If anyone else experiences low progesterone in back to back pregnancies and is there anything you can did to help that before trying to conceive again? Has anyone experienced a hemorrhage like I did during a miscarriage?
