Excruciating pain

I’m 7 weeks pregnant and I cannot lay on my right side at all or I get crampy! I gave it another try anyways and laid on my right side and not even 3 minutes into it I started having bad cramps where it was hard to breathe and too painful to move, it took about 5 minutes to sit back up because it hurt everytime I moved. I finally got sat up with the help of my amazing fiancé and the pain immediately toned down but I stayed crampy for about 5 more minutes, this is my first pregnancy so of course I assume the worse. Any other mamas experience this and baby is okay? Just need to put my mind at ease and can’t ask anyone because we haven’t told anyone yet 😭
