Spd or round ligament pain gets worse once you hit this point. I agree to mention it to doc...just in case it is Spd. Only thing that helps even a little is taking the transition from sitting to standing really slow and to do stretches...pregnancy stretches like small lunges.
Sounds like spd I've been suffering with it since around 19 weeks. Have a google of it and see if this sounds like you, if so speak to your doctor next time your home or at your next appointment as physio and painkillers are really the only things that help especially as it starts to get worse the further along you get
