Is it possible to have pelvic girdle pain from about 19 weeks of pregnancy or is that too early? I’m 21 weeks and about two weeks ago I had a day where I did a lot of walking in a hilly area. This lead to a twinge in my lower back area, which since then has developed into agonising pain in my tailbone/bum area whenever I take a step. It’s also agony to turn over in bed, to get up from sitting and to get dressed (putting pressure on my right leg is when it really hurts)
I thought it might have just got better by itself but it’s been two weeks now and is really getting me down. I’m normally a very active person and had been exercising all the way through pregnancy with no issues, so now not even being able to walk short distances is really depressing. I’m back to work next week after the Easter holidays and I don’t know how I’m going to cope, but being signed off isn’t an option because we don’t get paid for sick leave 
Anyone have any experience of this or know any stretches or exercises that could help?
