Sciatic Pain Pregnancy

I'm really at the beginning of my pregnancy (eg 5 weeks) and I already noticed the pain of the sciatic nerve every time I spent some time walking. This is my second pregnancy with my daughter I did not until I was about sciatica seven months pregnant and I think it was because of all the weight I was carrying. Is it normal to have this so quickly?

Oh yes! I had the same thing with this pregnancy ... it was the baby getting bigger and moving all your organs and grows into something on your sciatic nerve ... it will disappear, then come back later .. LOL
GOOD LUCK

Im pregnant with my second too, and I got it early this time so ... I didn't have it at all with my son, but he had an injury when he was a baby and he hadnt had since recovered. Do you see a chiropractor? Ive seen a whole in my pregnancy and has certainly contributed
