Started having pain

Alison • Hi. I`m a 30 year old mother of 2 (boy 10 & girl 5) I had a mc 9/2014 & I am currently pregnant with our rainbow baby.
Starts having pain on my lower left side just above pelvic bone & was kinda worried. Got out my Doppler & looked around for baby to find it right where I was hurting. It must be moving and stretching good down there for 11 weeks 2 days. Don't remember this with my other kids.
