16 weeks 2 days no more sore boobs

I’m 16w 2d today and I have a history of recurrent miscarriage. This is the furthest along I’ve gotten. Up until now my boobs have been hurting ... at around 10 weeks it stopped but then started again and they were painful today. Well, now I just literally noticed the pain is gone. They no longer hurt. I also just took a plane to visit family. I was cleared to fly but now I’m worried maybe flying caused something to happen and I’m having another Missed miscarriage. Anyone ever had a decrease in soreness around 16 weeks....Trying not to freak out but this is what loss does.
