Brief Answer: You should take a urine pregnancy test at home Detailed Answer: Hello! If you have unprotected intercourse notably about the time of ovulation chances for pregnancy exist. The details given are insufficient to predict your days of ovulation and the timing of intercourse. Therefore you should take a urine pregnancy test at home to confirm/rule out that you are pregnant. If the test is negative delay periods may come from many causes like : excess stress hormonal imbalance loss or weight gain, etc. If pregnancy is negative, I would start you on duphastone or uterogestane for 5 days to promote the periods to come. Take care of your self and do not worry
