Please tell me what you see 😣😣😣

I had an ultrasound on Friday the 10th. Doctor told me all he saw was gestational sac and yolk sac at this point but that i can still very well be too early, one app says im 7w4d today and another says im only 6w5d. Is this normal? Please help me out im freaking out sooo bad my anxiety hasnt let me sleep nor eat 🥺
