How far along am I?

Sara • We are pregnant with our rainbow baby due in early July 🙏🏻
So my last LMP was October 6 and I either ovulated the 24 or 31 of October. My clear blue weeks estimator said 3+ yesterday and according to the packaging, it will only read 3+ once your hcg is above 2,600. Can anyone help me with the timeline? I have my first appointment on December 1 and I'm really hoping to see or hear a heartbeat to ease my mind due to this being our rainbow baby.
