Relaxin hormone is softening your ligaments to prepare pelvis for birth, which strains your back muscles. Try doing gentle pelvic tilts and avoid standing for too long at a stretch.
A mix of hormonal changes and physical weight gain causes this strain. It's a very standard symptom, but if the pain is radiating or too intense, definitely get your doctor's opinion.
Oh god, even I am facing this since week 18! Is it normal to have lower back pain so early? I get scared thinking if I am doing some wrong posture while sleeping.
My app says back pain peaks in the 2nd and 3rd trimester because of the hormone relaxin and shifting posture. Try tracking your daily steps and sleeping on your left side with a pillow between knees.
Haha, welcome to the club! Your center of gravity is shifting and your baby is basically using your spine as a pillow. Get ready for some funny duck-walking soon.
It is so tough, I remember crying because of severe backache during my 8th month. Your body is doing such a beautiful but hard job of growing life, so please rest as much as you can.
