Severe back pain

Ni2 ❤

Hi friends, I am 4 weeks and 5 days today and i am having a severe lower back pain from yesterday which extends to the butt and to the legs. It is very worse when I am lying on my back. I have had backpain before but the one i have now is too strong. I am scared. Is anyone else in my same state?😐 I also have a pulling sensation or may be can call it as a mild cramp in the left side uterus...at night my problems are worse.
