Just some comfort really

So I had a chemica back in may witch I could just feel there was something wrong ! Now I’m 6+4 today and had a scan seen the heartbeat! My problem is I feel like something bad is gonna happen again ...😩 is it because iv had a previous loss or is it my gut instinct 🤷‍♀️ has anyone felt like it’s gonna go wrong and everything has been fine and a healthy baby?
