... and sometimes I will forget to take it On a regular. In November 2014 I last had sex with my bf, then in December I had a regular 3 day period, and in January 2015, I spotted for one day only, and so now since February 2015 I haven't start my period, but I've gained weight since I haven't got my period. I did stop the pills since I have notice the spotted one day period. Am I pregnant or no?
