Help! Advice please.....🙏

Sooo I have my first dr appt at 8 weeks on Friday. I’m super excited but nervous. My partner is going with me but I’m nervous they are going to mention a previous miscarriage that my partner does not know about. Without going into all the details it wasn’t his child that I miscarried and did not think he needed to know about it and did not believe it needed to be brought up. I didn’t know how serious we would become at the time and I just want this to be a happy time for us. How can this be avoided. Thank you ! Any advice is welcomed and appreciated...
