Shoulder Pain Early Pregnancy

So about a week and a half ago I had severe right shoulder pain that felt like a pulled muscle. I had no clue at the time that I was pregnant. I found out the 27th of December. So I know a sign of an ectopic pregnancy is shoulder tip pain but is it consistent? My shoulder hurt for about a week on and off and is completely gone now and has been gone for over a week. I have no bleeding or other signs of an ectopic pregnancy so should I be worried about my old shoulder pain? I believe it was a pulled muscle but just curious.
