Scared to try again

I just miscarried a week and a half ago at 7.5weeks. I'm so afraid to start trying again. I lost so much blood and was in so much pain that vicodin was barely relieving it. Worst experience of my life. I'm scared that if I get pregnant again the same thing will happen. I started spotting at 5 weeks and it just went downhill from there. My thyroid is a mess so I'm blaming that.

TTC is literally the hardest thing. Its heartbreaking.
