Hi. I had unprotected sex on 9th of July and the last cycle date was 10th of June. This month I have missed my periods even after having an I-pill. I have had mensoherit forte for three days for preponing the periods and later pimolut-n for 3 days. But still I haven't got my periods. The pregnancy test result is negative after 12 days of intercourse. Culd I be pregnan? O no?

Take some more tests, one test is not reliable. Also, if negative a second time, wait a few more days (due to the difference in hormone values) and try again and see if the result has changed. Missed periods do happen sometimes, just take the tests as it is the only way to be sure.

A test 12 days after a period is way too soon. Wait until your period is at least 2 weeks late, then test using first morning urine.

I'm assuming the I-pill is a morning after pill. If so, know that that can also throw off your period.

Bottom line, no form of birth control is 100% effective, so any time you have sex, pregnancy is possible. You'll have to test at a later time to get an accurate result.

Good luck.
