Anxiety

9 weeks tomorrow and the next 2 weeks is crucial for me. Had 4 previous miscarriages and the furthest I've gotten is 9 + weeks. All 4 were different reasons. Seen heartbeat at 8 weeks 1 day midwife said everything looking great no cause for concern, but yet I haven't been able to relax. I feel like this pregnancy is different and I do think positive but now and again I have extreme anxiety and have to sit down and breath through it. I'm so nervous for my next scan a week on Tuesday I pray everything is good. Any positive experiences from other ladies would be great if you could share them? I try to explain my concerns to my close friends and family but I sometimes feel I go on and on and I annoy them lol.
