I want to hear the heart!

So we have a heart monitor from when we were pregnant with my son. We let my brother in law and his wife borrow it when they were pregnant. I'm now 9.5 weeks pregnant and been asking for it for a month and they FINALLY got it back from a friend they lent it to. We will probably see them this weekend but I want it tonight! We haven't had any appointments and I really want to hear this bbs heart. My brother in law works 7 minutes from our house but didn't bring it by 🙄 would you go get it or be patient and wait a couple days 🤔 they live about 15-20 min away
