IS THIS NORMAL!!

So, I’ve recently gone on the combined pill to regulate my periods and help with cramps. But on the second day in which I took a pill, I struggled to breathe the whole day. I had to run out of class because I literally couldn’t breathe, and there were sharp pains in my stomach and shoulder.

I’ve never experienced these problems before, should I make an appointment to speak to my GP, or will theses problems go away in a couple of months??
