<s>[INST] Hi I have been on birth control constantly for about 7 months now. I had a UTI almost a week ago and that has cleared up. My period is due in about 10 days and I am having pretty bad back aches. I had a BM today (first time in about 3 days) but I feel constipated. My stomach feels slightly hard all over. I also took a home pregnancy test last night and it was a very clear negative. Could i have an ectopic pregnancy? What could be the cause of my lower back pain? [/INST] Hi-If i would be your treating doctor I would advise you to take triphala churna 1-2 tsp at bed time for constipation.-your urine pregnency test is negative so there is no chance for ectopic pregnency.- for delayed periods i would advise you to take tablet for withdrawl.This medicines are not given without prescribtion.so consult to local doctor or gynecologist. </s>
