Any thoughts or advice?

So yesterday I had some pretty frequent cramping on my right side (ovary, pelvic bone, etc.) They weren’t hurting necessarily more annoying and uncomfortable. Last night when I was trying to sleep I rolled onto my right side and had two quite sharp quick pains. Of course I immediately thought worst case, however, there were not spotting or blood and it only happened those two times. Then I woke up this morning with pretty much nothing up till this evening. But just now, I’m trying to get comfortable on the couch and rolled on my right side and felt the same sharp pain real quick. I feel fine now, I just don’t know what to think. I don’t have my first US until Nov 5th and I’m freaking myself out. It seems to happen more often at night and when I try to lay on that side. Anybody have any idea?
