Advice needed

Ca

My LMP was 8/27 - we were <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> or anything

So based on that I’m 8w1d

On 10/11 I went for early ultrasound

Empty gestational sac showing 5w

10/20 I went for repeat. Sac showed yolk sac and fetal pole. Heartbeat of 112. Measuring at 6w

I had spotting and went to the ER today

Baby shows 6w1 day, heart rate of 75

I was discharged and said to follow up this week with OB

They told me “everything looked fine”

But… it’s heart rate dropped and seems like not growing on track :(

Anyone go through anything similar?
