Finally got a BFP... Now what?

After exactly one year of TTC, two miscarriages, and a hysteroscopy, I'm finally pregnant again! But a moment of joy has turned into anxiety and stress. I'm so scared of miscarrying again. Insurance wouldn't cover testing after ONLY two miscarriages (such a joke), so I have no real different game plan for this pregnancy. I am calling my doctor today and seeing if I can get on baby aspirin and progesterone. Any other suggestions?
