SCH getting bigger

Casey

At 7 weeks, I was told I have a 3 CM SCH. I just went in for my 10 week appointment and was told it grew to 7 CM but that I have a viable pregnancy. Does anyone have any stories about theirs growing and then shrinking? I’m nervous this isn’t going to end well. I am limiting movement for 2 weeks until my next ultrasound, but is there anything else I should be doing?
