At 16 weeks, some stretching and heaviness around the pelvis and lower back is common as your uterus grows, especially with your endometriosis history, since old scar tissue can sometimes pull as things shift. Normal scans and tests so far are reassuring.
Next Steps
Keep track of when the pain feels worse, such as standing, walking or certain positions. Please mention this to your obstetrician at your next visit, given your endometriosis history.
Health Tips
Go in sooner if the pain becomes severe or constant, or if you notice bleeding, fever or reduced baby movements.
