hello
delayed periods r sign of pregnancy in sexually active woman with previous normal regular periods but they can happen in other situations like stress,
thyroid disease,
hyperprolactinemia,
polycystic ovarian disease how was ur previous menstrual history were they regular
since u r sexually active & not using
contraception for 2 months pregnancy remains a possibility
brownish discharge with delayed periods could be due to
missed abortion, ectopic pregnancy or just premenstrual spotting in non pregnant women
ur upt is negative have u done it with first morning urine
if not please repeat upt with first morning urine sample
if repeat upt is positive ( test & control line equally dark in color ) please go for ultrasound to confirm viability of fetus & to rule out missed abortion
if repeat upt is weakly positive ( control line lighter than test line ) u need urgent gynaecological check up with bhcg & ultrasound to rule out ectopic pregnancy
if repeat upt is also negative u should go to gynecologist who will prescribe u certain test & medicines for periods to come after examining u
hope this could help you
