I'm 5+3 so really early only found out a week ago. Been fine really. Slightly tender boobs, no sickness or anything (yet) but since this morning I started with lower left sided back pain only on the left side and in one spot. It went off for abit but now it's come back and all across my lower back and feels quite tight? Almost like I'm being squeezed from both sides of my hips. It is quite painful atm but I don't want to take any paracetamol yet as I want to see if it gets even worse. Has anyone experienced this crushing sort of lower back pain in early pregnancy and all has been okay??
