I'm not sure when I was supposed to get my period this month. I did have it last month very very light and only for 2 days. There has been a few days when I've been feeling really sick..not everyday though. My nipples are really sore and I've been peeing a lot. My back is sore and I've been very tired. All the signs are pointing towards pregnancy. The catch is, it's been close to 3 months since the last time I had sex. Is it possible that I'm pregnant and only finding out now? If so, is it normal for symptoms to only start appearing after this long?
