Hello, my age is 26 and married. Me and my husband trying to conceive since since two months, My last Lmp is 2 june,2016 and we had unprotected intercourse during my ovulation and then as i was expecting my pregnancy i did test to confirm pregnancy using home pregnancy kit test before my menstruation which were expecting on 30 june,2016 ( as i have normal 28 days menstrual cycle) but it came out to be negative. but i didnt get my periods and now since yesterday i have left lower abdomen cramps and today morning, i saw spots of dark blood on my pantyliner and since then i changed my sanitary pad and see very light bleeding and pain on lower left abdomen. so my question is am i pregnant? why i have delayed periods if i am not pregnant? why the color of bleeding is so different?
please help me i am worried.
