lower back pain lupus

ok 15 weeks of pregnancy?
been having back pain and pain in his right leg, ugh come and go, but for some reason today I couldnt even walk by pain, i do not know if you have something to do with the belly every time because there is great doubt at all: S … not all the pain because the ligaments should not last longer a few seconds, and another thing is that I'm pissed (no lie, as every 15 minutes and after i urinate I feel a pain in the lower abdomen as less than a minute? I have lupus (Antimmune disease) so bad prollly going to have to go to hospital, but I wonder if anyone has experienced this pain? or something
is best to consult to a doctor about it, no conclusion about the signs and symptoms that occur as it could be misleading and confusing after a while, the doctor is only alone can draw conclusions
