5w pregnant & ruptured corpus luteum cyst

I had gone to the hospital for an u/s yesterday to determine my extreme abdominal pain and why I passed out in the bathroom. Turns out I had a ruptured corpus luteum cyst. I am only 5w pregnant. Everything I have read about the corpus luteum cyst insinuates that I need this in order for progesterone to be available to my developing fetus. They did see a 5w gestational sac on the u/s yesterday that looked as well as could be expected, along with a pocket of fluid where my radiologist believes the cyst had ruptured. They reassured me everything would be fine and this doesn't put the baby at any risk, but I had a miscarriage in April and everything makes me freak out more than normal at this point. Do I need progesterone supplements until the fetus can make it's own progesterone? Am I at greater risk for miscarriage w/o progesterone this early along? I am waiting for a call back from my midwives, but am covering as many bases as I can in the meantime. Thanks,
