Overthinking first time preggie

Hello, just found out that I’m 6 weeks pregnant on Letrozole after 2 years of TTC 🥹 The feelings are overwhelming! Gynae appointment is scheduled on 30 Jan.. this 2 weeks wait is so hard! I can’t help but overthink if baby is well or what’s going on in my womb and it makes me stressed and worried 😳 I don’t have morning sickness symptoms except for sore boobs and cramps. Anyone mum to be/mums have advice on overthinking? 🥺
