could i be pregnant?? helppp.

Amanda

Me and my boyfriend have a 2 year old daughter and have been talking about adding another in about a year. We dont use any birth control just the "pull out" method and the past few days ive had horrible gas and for the past week ive been extremely tired, taking naps every chance i get, fatigued, and my nipplea are very sore. I'm due for my cycle tomorrow but i just have "that feeling" that something is off. any advice helps!
