I'm 18, and my fiancee already has a 9-year-old boy. We both want a baby, not really trying, but still. I usually have my period between 22 and 26 days apart. Tomorrow will be 25.

My breasts are VERY tender (I can't put any pressure on them, they hurt when I TOUCH them), I have at least 3 dizzy spells a day, I have a slight discharge, cramps where they never were before,and I get very nauseous, but not throw up.

I was wondering how long to wait before I take a pregnancy test, and if another 3 weeks would help it along.
