Pregnancy related???

I'm 15+4 and I started having this sharp pain in the top of my right shoulder. It started like 3 days ago and every time I take a breath it feels like an intense stabbing pain. I have tried Tylenol, ice packs, and heating pads and so far nothing is helping. I started looking on Google (which was probably a bad idea) and it said that it could be a sign of preeclampsia. Obviously that's worse case and I don't think it would show up this early but I'm to the point of having my DH take me to the ER because the pain is waking me up in the middle of the night. I really have no idea what it could be. Has anyone heard of this or experienced it? Thanks!
