Ma'am I had unprotected sex with my girlfriend on 27 August and she took I pill (ecp) after 6 hours. After 4 days I.e. On 1st September she started bleeding and she blessed for four days. Now after 21 days of intercourse, we did 4 home urine pregnancy test which were on 18 September, 25 September, 2 October and 9th October. All the results were NEGATIVE. We even did a bhcg test on 18th October that was 51 days after intercourse, the results were <1.2 miU/mL. Then she started bleeding from 23 October to 29th October. This month also, The bleeding started day before yesterday I.e. On 23rd Nov. My question is can we rule out pregnancy now because I have read on internet that sometimes you can bleed during pregnancy. So can I rule out pregnancy or do we still have to worry. Please help.
