Sharp cramp and pain in lower back (almost butt)

So I was squatting down at an appointment to have my sons one year pics taken and got a quick sharp pain in one side of my lower abdomen... of course I instantly worry. It faded fairly quick and then it seemed I have really lower back pain on one side near my butt... no blood/Brown/pink anything... and no more cramps but still nerve wracking... not sure if it was just from my position squatting or what but scared me nonetheless! Seems to hurt when I shift weight too... who knows... cramp may have been unrelated to the back/butt pain. I can’t wait to get out of this first trimester ☹️
