Measuring 6 weeks at 8 weeks

Ma

Hi mamas! I’m looking for some reassurance. I’m 40 and this is my second pregnancy. I had my first ultrasound yesterday and the doctor said I was measuring 6 weeks 2 days. The heart rate was 189. Dr. said everything looked healthy and my pregnancy was fine, but I am overwhelmed with anxiety. We had sex ONCE that cycle and my period is very regular. My calculations put me at exactly 8 weeks. 6 weeks 2 days means I conceived 4 days before my BFP. This is nothing right? The baby is just measuring small? And that’s okay? I left the doctor feeling okay but then I was flooded with worry about the heart rate being too high, then the baby measuring small…I normally take medication for anxiety that I’m not taking now and I THINK this is my anxiety (and not reality) producing these overwhelming nervous feelings. It’s just really hard to not believe my own feelings. And it’s hard spending hours searching the internet for an answer. I have a call into the doctor but I’m just wondering if anyone else has experienced any of this? Baby measuring 2 weeks smaller, heart rate high, anxiety?? I’m just really struggling right now and could use any sort of support.
