BACK PAINS?!

An
Ladies! 
I am currently 15 weeks and as of 2 days ago or so I started getting these really bad lower back pains! From what I thought, isn't this supposed to happen when your farther along in pregnancy? Have any of you experienced something similar?
Pain feels SHARP like it starts on my lower back right side and goes to my tailbone. I feel I'm getting a cold so every single time I sneeze it hurts or if I bend a certain way. Just not sure if this can be from the pregnancy or maybe something else! It definitely is painful 😖 Thanks to anyone who responds!
