Is this normal?

Rhiannon

I’m 21 weeks tomorrow and I haven’t done anything out of the usual today but I’ve just noticed some pain on my right side. If you were to put your hands on your waist it’s about half way down to my hip that it’s hurting and it sort of goes around my back a little bit. Feels a bit like I’ve pulled a muscle and hurts more if I twist certain ways. I’ve also had a few dull aches in my groin, by the left side of my pubic bone. I can still feel my girl moving. Is this normal or should I be going in to get checked?
