Me and my girlfriend had unprotected sex on 27th July and she took unwanted 72 after half an hour. She had vomiting after 3-4 days and on 3rd august she got brown few drops of blood (only few drops 1 2 drops) on 4th she had little normal kind of dark red bleeding it continued with normal blood colour and very light flow till 6th (it had no clots. She took a home pregnancy test on 10th august and it came back negative. Her periods was due on 14th aug. On 15th august she took test and again the result was negative again on 23rd she took a test and it was negative. It?s 26th aug now and she hasn?t got any bleeding yet Is she pregnant or the bleeding she got on 3rd what was that?
