17 weeks & 5 days pregnant 😁 anxious feeling!!

Hi everyone I'm 17 weeks + 5 days this is my third pregnancy. I sadly had a stillborn in march this year at 39 weeks + 4 days, I didn't think it would begin till later on in the pregnancy but I feel very anxious slightest thing and I'm worry about going hospital, this week I have had slight spotting and cramping a lot I have been hospital and they listened to heartbeat and sent me home I still am very scared as  this spotting and cramping has been going on for 3 days now and I'm not sure if I'm just worrying more due to what has happened earlier this year. Has anyone else been through anything similiar and feel they could of been at the hospital on a daily basis?? Thankyou in advance xx
