Bad lower stomach and back pains 😣

I'm 10w 4d and this is my first pregnancy, so everything is super new to me!! For the last 48 hours I've been experiencing really bad lower stomach and lower back pains that kept me up all night and when I walk/ get up from being sat down they get worse. When I called early pregnancy unit to seek advice they told me to take regular paracetamol every 4 hours for 24 hours, but the pain has still not eased or improved. What do I do?! 😞 Have any of you experienced similar pains at 10 weeks?
