I started on the pill again after a month break and started it on my first day of my period (29/10/15). I had unprotected sex with my partner on the (7-8/11/15) and on 13/11/15 I noticed a light pink blood and 14/11/15 it was light brown blood and till now I'm experiencing between dark brown/bright red light period with the presence of mild-moderate cramping.

Is there a chance that I may be pregnant?
