Ultrasound and measurement advice

Hi all,

I went in for an early scan today as I had some vaginal discharge which concerned me on Saturday which led to an ER visit.

I had a miscarriage last year (blighted ovum) at 8 weeks so this discharged looked similar to that leading up to the days before my miscarriages happened.

Luckily it only happened once upon wiping. The ER department were happy with my bloods but said they would give me a referral for an early scan to keep my mind as ease.

I went today and saw my little bean on the screen. I am supposed to be 6w 4days but am measuring at 5weeks 5 days with a heart rate of 101bpm.

Just want to get advice. Has this happened to anyone ? Is this a normal HR ?
