When does relaxin hormone start in pregnancy?

Relaxin starts working really early, even in the first trimester. That's why you might feel your joints are a bit looser or get hip pain. My daughter had this, and we made sure she wore supportive shoes and avoided heavy lifting to prevent injury.

Oh, I didn't know about relaxin before! So it starts right in the beginning? Does this mean I should be extra careful with my movements from the very start, even if I'm not showing yet?

Actually, relaxin starts super early, like from the first few weeks after conception. I remember feeling my hips and pelvic area getting a bit achy much earlier than I expected. It's just your body getting ready for everything.

Relaxin production begins in early pregnancy to soften the cervix and pelvic ligaments. It's a continuous process throughout. This means you need to be mindful of your posture and lifting from the get-go to prevent discomfort, especially if you have an active work life.
