I’m concerned, please help

Kimberly

I’m currently 9w5D but baby is measuring 10w2D

2 days ago my babys heartbeat was at 166 and today it’s at 162

Is this normal? Please let me know if that’s has happen and if it’s normal? This is my first pregnancy and I’m really worried

Does it mean miscarriage? 😨🥺

I’m super worried it came down 4 in just two day?

I saw my baby today and baby was super active and moving a lot

Please let me know
