10 weeks 4 ultrasounds

Claire • 31 years old ttc with my partner of 9 months after being friends for 15 years. Spent 3 years on the implant with no cycles. First cycle arrived 28 days after removal and hoping to fall pregnant soon x
I have had 4 ultrasounds and I am 10 weeks today. 3 by the hospital due to previous mc and a bleed with this pregnancy and 1 private ultrasound to reassure me at 6 weeks. We've heard the heartbeat on 3 occasions 7,8&9 weeks. 1st ultrasound was to early for that . Baby is growing well and my dating scan is 30 June. Would you announce it now or wait until next scan?
