I had my periods from 5th to 9th January and then had unprotected sex (though he pulled out and ejaculated much later outside) on 13th January. On 25th January I got some brownish discharge (very minimal) for around a week with thick clear mucus. I had my period date on 5th February but haven't gotten it yet. I took two pregnancy tests on 6th and today morning (almost 4 weeks after unprotected sex) and both came as negative. Can I still be
pregnant? Why are my menses delayed?
