Very nervous

maddison • 👩‍👧🤰🏻

So today we went for a heartbeat scan and found out we we’re having twins. I’ll post photos. I have some questions so the dr told us there’s obviously two separate sacks but they share a placenta. I’m worried cause baby a had a heart rate of 140 and measured 7 weeks exactly (and that’s how far along we are ) and baby b had a heart rate of 121 and measured 6+2. I was wondering if this is normal and okay and if they will 100% be identical twins or not ? I’m less sick this time around then I was with my singleton which was a girl I’m just pretty tired super hungry my boobs don’t even hurt but that may be because I got my nips pierced a few months ago lol. But I also have 0 acne which is rare I’ve always had some pimples even if they were just colorless and on my hairline but for two weeks or more I’ve had NONE at all which I’m thankful for. Thanks for any advice or input.
