I'm miscarrying 😢

Abbie
So I'm supposedly 11 weeks 3 days and had some bleeding so went for a scan today and it's measuring 6 weeks with no heartbeat. They said my dates are either way off but I'm pretty certain of my dates as we used ovulation sticks and haven't had sex since conceiving because we've been too worried, and 5 weeks is a lot to be out by!! Or I'm starting to miscarry. Have to wait until the 14th to have another scan and see if it's grown or disappearing but bleeding is getting worse so not holding out much hope. Obviously wasn't meant to be but I'm so devastated 😢 xx
