Very first positive test!!!

Hi!! I’ve been ttc for a year on and off and I got my very first positive test!!! It still doesn’t feel real. I haven’t gotten my period yet either (due in a few days). So im just really worried. I keep getting a lot of cramps and twinges which Ik is normal but im still so worried im gonna either get my period for some reason or im going to miscarry. Please tell me I’m not alone!! Anxiety is high I’ve been praying for this and it just feels too good to be true!
