Freaking out!

I'm in early pregnancy and managed to capture a few of the early pregnancy symptoms...nausea...sore boobs...odd bit of cramping....frequently peeing.... Now all those symptoms have gone?! Is this normal? is it ok? One of the reasons I'm freaking out is that exactly this date 3 months ago I miscarried and my symptoms disappeared and I knew I wasn't pregnant straight away... I haven't bled or spotted and in my heart I feel I must still be pregnant as nothing bad has happened. Would appreciate any advice you girls have to give! Xxx
