could this be my rainbow baby❤❤❤🌈🌈👶

I've had lower right abdominal pain, tender boobs, headaches, cravings, fatigue, sickness (morning &I evening) itchy nipples and I've noticed my belly bar doesn't feel as comfortable anymore 
I've took a test and I'm sure I can see a line and so can other people who I have shown. 
Just looking for opinions 😊 not long got over a miscarriage, so could this be our rainbow baby-currently trying :) 
Thank you for your opinions ❤😊
