Symptoms

So I found out I was pregnant about 3 weeks ago. I’ve had very consistent symptoms including persistent nausea and food intolerance. 3 days ago it’s like my symptoms just went away. I still have bloating and my boobs are tender but nothing else. I also have had mild cramping. No bleeding or spotting. Yesterday I had my first ultrasound and heart beat and baby were seen and everything seems okay. I’m just anxious and worried something is wrong. I still don’t have symptoms today either. I am currently 8 weeks pregnant. Has this happened to anyone else

Sincerely anxious first time mom
