5 weeks+1d and heartburn 😫

I'm 5 weeks and 1 day today and noticed I'm getting a lot of heartburn. Especially when I lay down. It's driving me crazy. Also my boobs feel huge-sore. And nauseous here and there. I keep craving spicy food. I keep thinking maybe it's a boy 👦 💙🤗 with my first, my son. All I wanted to eat was spicy food. Everything tasted plain. Like now. With my second wanted nothing but sweets and she was a girl. My 3rd ended in a chemical pregnancy and miscarried at 4 weeks 5days🥺💔 this will be our rainbow 🌈 baby 👶 and even though my anxiety is off the roof constantly check to see if I'm bleeding, this baby gives me hope and I'm praying 🙏 this little nugget is a sticky bean in there. I feel like time is going by so slow. I want it to be next week already so I can get an ultrasound. I got a ultrasound done at 4 weeks 5days and they were able to find the gestational yolk sac this time just no heartbeat yet which I know it's way too early. And my numbers were 5,000+ so just keep on growing in there baby. What are your symptoms at 5w+1d. Please share. 🤰👶👶👼🌈
