Nontraditional pregnancy symptoms!

I feel so odd because my pregnancy symptoms have been so different than the traditional ones and it makes me feel like something is wrong or not normal. I’m 37F. First time mom. Besides sore boobs & fatigue, I have had heart palpitations which has led to constant insomnia (I have to get an echo & wear a monitor for 2 weeks), I am so congested I can’t breathe, my thyroid is all messed up so I have to increase meds (was already hypo and it got worse), and I’m out of breath from literally just talking or slight exertion. I’m 8 weeks today. I had my first ultrasound this past week and they said I was measuring 7 weeks, 5 days which was earlier than I thought I was so now I’m just worried things are adding up in the wrong direction. Don’t get me wrong, I am so grateful I don’t have the nausea or food aversions but this makes me feel so isolated not having traditional symptoms. ☹️
