what are some early symptoms of multiple pregnancies?

I had <a href="https://glowing.com/glow-fertility-program">IUI</a> with two good eggs I have 2 positive home pregnancy tests that were faint. A dream a week ago where when I went for the ultra sound they showed me two babies hugging in my womb. I'm also having spotting and pricks of pain on both the left and right of my uterus.. Any ideas out there or am I just over thinking it?
