worried momma to be after miscarriage

Cecilie • 25 mom of one baby boy whose name is Knox Maverick. ❤️
Am I the only one who constantly worries about having a recurrent miscarriage? I am driving myself insane to the point I am miserable. I went to get another scan at 5 weeks 3 days (sac measured 5 weeks 1 or 2 days can't remember) and all she seen was the gestational sac. It did, however, grow a good bit from my four week 3 day scan but still no yolk sac or fetal pole. Is this normal? I am getting monitored for my corpus Luteum cyst I have on my right ovary. AND that doubled in size from last week. I'm on 400mg of progesterone (orally)  every evening before bed. Help me not worry!!! Google is my worst nightmare.
