Hi there...it is difficult to tell if you are
pregnant just from that history. You Will have to take a urine
pregnancy test to confirm it. Urine pregnancy tests are usually positive 7 to 1p days after implantation. So it is better to take pregnancy test 1 week after the missed period. Sometimes spotting can be seen in between cycles. Also you must consider that there are even other causes for missed menstrual cycles like pcod, stress, fibromas, drug intake. So kindly consult a obstetrician for further evaluation.
