1st pregnancy emotional & anxiety

Hi I’ve never been pregnant before delighted I am pregnant got pregnant fast , can’t fully believe it yet! The clear blue test says I’m pregnant & according too this app We due 30th January 2019 so only 5 weeks in oven!! Lol we told our families already not even known a week yet, I’ve booked 1st midwife appointment but have wait till 12weeks before scan I think then it will feel real. So far I’m emotional over everything & anything I’m full of anxiety over what I can and can’t do scared of doing something detrimental too the baby. I’m bloated more than ever and feel totally knackered all the time. Hope not just me feeling like this? I want this baby happy & healthy and 2019 can’t come soon enough.
