Thank you! First pregnancy jitters are the worst :/ I question every single little thing and I hate it.
Maybe your body is producing a lot of that joint loosening hormone. That's how I felt through half of my second pregnancy.
I've also been experiencing pain down below and my left side is actually swollen. It also hurts more the longer I'm on my feet especially at work standing for long periods of time. Went to my doctor and found out its varicose veins and will go away after I deliver. I'm 35 weeks now and it's been going on since about 25 weeks.
Talk to your doctor about it. Have a safe and blessed pregnancy :) <3
