pregnancy after miscarriage

Please someone ease my nerves if you can! Just had a very very faint positive today.  I had a miscarriage two years ago, and as happy as I am about the positive my nervous are getting the best of me. I'm having some cramping very slight. Now I'm realizing I'm so early on that I'm not yet excited 😞 I just want this so much. I need my fears of loss to subside . I'd love to hear some positive experiences with rainbow babies! Thank you ❤️
