Anxious and scared!

Hello ladies. I just found out I’m pregnant! This will be my husband and I’s 4th pregnancy..first was a miscarriage at 8 weeks, then 4months later I found out I was pregnant with my now 3 year old and carried her for 41 weeks! 11 months after having her I found out I was pregnant again and the day after my 37 week checkup my placenta abrupted and my sweet girl was born sleeping😔 that was 2 years ago..I’ve been back and forth about trying again because I’m just terrified now of something happening to another baby. I’m now 6 1/2 weeks with light cramping here and there but really no other symptoms yet..I have a doc appointment next wed for U/S and many more to come since I’m at high risk now. Does any of you ladies have any success stories after an abruption to keep my mind at ease..? I’m trying to stay positive but with my past experience it’s very hard and I want this baby so bad already! Also I’m worried I’m not showing many symptoms yet I know it’s still early but praying it’s not a sign of M/C😩😭
