Horrible pain in my right leg and back? 😫

So I’m currently 14 weeks and I’ve had back pain since about 6 weeks... but yesterday it took a turn for the worse. Every time I step I get a sharp pain (almost like a pinching/stretching pain) through my lower back all the way down to the back of my right thigh. It’ll go away for a bit but as soon as I stand up or move the wrong way, it happens again. Has anyone else experienced this? It’s really painful and I’m just trying to find some relief. I’m tempted in calling my doctor and letting her know what’s going on because I don’t know how much more of it I can take if it doesn’t go away. 😣
