20 pounds in two months is a lot of weight to gain in that short of a time frame, i myself am 17 and the only thing that i have done do gain weight that quickly is to take body building supplements such as multiple brands or forms of tren or tren extreme, or creatine, and steroids are not out of the question with gains that drastic. either hes been eating behind your back or hes taking something to enhance his ability to gain muscle so quickly.

That would be very unlikely. Weight gain for most pregnant women is an average of 30-35 pounds over the nine months. The first 10lbs will usually take three whole months from time of conception.

Most importantly, recognize that having your monthly period return is the most certain sign that you are not pregnant.
