Anyone else really anxious after Miscarriage?

Dani • Pregnant with fraternal twins!👶🏼👶🏼🤞🏼🌈☔️3 losses now👼🏼👼🏼👼🏼1 precious Daughter👸🏼
Hi ladies, I am literally 4 weeks pregnant (1 healthy 2 year old) but I have a history of miscarriage.. 1 when I was 16 (around 6 weeks) and one around 8 months ago. I had no bleeding or signs I had miscarried, just went to the 12 week scan to find our baby had no heartbeat💔 
I feel like I can't get attached to this baby as I am so scared that the same will happen again, I'm obsessing over making sure I'm as healthy as I possibly can be and I know there is such a long way to go until I'm 12 weeks again😢 
Does anyone else feel this way? Have you got any advice on how to cope?
