Lack of symptoms at almost 12 weeks

I should be 12 weeks tomorrow. My last ultrasound was at 10 weeks and it was a great ultrasound. However, I’ve also had three miscarriages prior and had never gotten past 8 weeks. This was a big milestone for me and I was relieved at the time ... but for the past week my symptoms have literally gone away. I never had nausea or any sickness this whole pregnancy , I had very sore boobs up until 10 weeks. No more bloating and I lost 2lbs. Not sure what to think. I’m hoping that chances are everything is ok and the placenta has taken over but based on my history I’m really nervous. My previous miscarriages have all been missed so if something were wrong right now I wouldn’t know except. Anyone have a similar experience? I did hear the chance of miscarriage goes down after 10 weeks but I also am not naive to the fact that things can go wrong at any time. Thanks!
