Back Pain

So I just found out this week that is pregnant, I am super excited! I am only about weeks...My symptoms have started this week and hit me so hard, my boobs hurt super bad, nausea, and all that but today I’ve been hurting really bad in my back on the right side...I’ve read that back pain can be normal in early pregnancy but it’s really worried me...it’s not so bad that I’m in tears but it does hurt a lot, it feels almost like my sciatic nerve or something! Just wondering if anyone else has had any back pain like this in early pregnancy??? I’m just a little worried
