Yes dear, a little back pain is very common because of hormonal changes. Don't worry, just avoid standing for too long and use a small pillow for back support when sitting. Take plenty of rest, okay?
I had really bad lower back pain around my 6th week and was so worried. For me, resting on my side and keeping a cushion under my knees helped a lot. Every pregnancy is different, so that was just my personal experience.
It is quite normal because your body is producing hormones that relax your ligaments. I used to apply a warm compress occasionally which gave great relief. Just make sure you aren't lifting anything heavy.
Yes, it's normal as the hormone progesterone loosens your joints. My doctor told me that early back pain is common, but we should always inform them if there is any bleeding or severe cramping. Try to maintain a good posture while sitting.
I'm also 7 weeks pregnant and going through the exact same thing! My back hurts when I sit for even an hour. Are you also feeling any mild cramps along with it, or is it just back pain?
After a long wait, every single symptom used to make me super anxious, so I understand your worry. Mild back pain is usually normal as the uterus adjusts, but please check with your doctor to give yourself complete peace of mind. Sending you so much love.
