I was sus when my morning sickness didn't start (usually at 6 weeks). I also felt really strange/silly when I was organising a midwife and making plans.. looking back it's almost as if I knew. Then when I started spotting I just knew it wasn't good. I tried to convince myself that spotting can be fine (I had it with DS) but my gut just knew i think. I was very apprehensive going for my scan at 7 weeks and I'm usually really laid back about my scans... I just knew it was going to be an empty screen. Didn't make it much easier actually seeing it tho
