Could I be bloated or actually showing?!

Bridgett
Hello, I am pregnant with baby number two! I have no idea how far along I am! I have an ultrasound coming up March 3rd. My last bleeding was January 9th, but I was on Nexplanon and got it removed the 11th of January. Not sure if it could have been implantation bleeding or not, but I feel huge. Could it be bloating or am I already showing?!
