So I got the green light to begin cetrotide from my nurse yesterday and I have no idea why I was so intimidated lol! I watched videos online a few times and read other girls experiences which freaked me out a bit lol, but I didn't get a welt or any burning from the cetrotide. It was actually one of the easier injections since everything came packaged in the box and all I had to do was mix it and up voila done!
