3rd baby and I’m so nervous cause no symptoms

So normally I would not be so anxious but I am 6 weeks pregnant with my 3rd baby. I have 2 healthy boys however in between the boys I had 2 chemical pregnancies. I am now pregnant again my youngest was born 3/25/20 and completely paranoid if this baby is healthy or not. I’ve got like no symptoms besides kinda sore breasts and wondering if anyone else has had a lack of symptoms. I wasn’t so nervous with my first son but after 2 chemicals I can’t help but worry. I haven’t had bleeding or cramps and my first appt is 3/29.
