I have a lesbian for 16 years decided to change my life..I had sex various times unprotected in the months of April starting 3 days after my period & 3 days before. That night I went to bathroom I seen a spot of blood on tissue. I touch myself with the tissues again nothing. went to bed that night no sign of bleeding. While a work went to the bathroom seen blood on tissues none in urine. This happened 3to 4 times while I was at work but when I put a piece of tissues there ever time I went to the bathroom only spotting. That night I went to the bathroom only a spot was on the tissue but more blood came while urining. The next day the same thing light on pad but more blood came while urining. Normally I bleed heavy on my first and second day and it last for 7 days but my menustration was very light no cramps. Still not having cramps. And its still lighter than normal can I be pregnant?
