So for the past month and a half I have had pregnancy symptoms. My period has been pretty normal though. I have been constipated like 24/7 I get stomach cramps and dull pains, breast tenderness, fatigue, increase in hunger, mood swings, and faintness feeling. My boyfriend has been kind of pressering about having a baby. So I was thinking maybe because he stresses me about it and that causes me to think about it more.. so maybe my body is mocking the symptoms to make him happy or something. Please respond if this makes sense.

It's possible... but being constipated could also account for several of the things you are experiencing. Watch your diet... increase your fluid intake and fiber with fruits, veggies, whole grains. Ask your doctor about something over the counter if need be to help ease the constipation. Not enough fluid intake can also account for the fatigue, mood swings, and feeling faint.
If you think you could be pregnant, find out one way or the other.
