Hello. For a little over the past month, I have had weird symptoms. I've been nauseous, urinating frequently, fatigue, constipation for a few days at a time, & then diarrhea. My period is 20 days late & my boyfriend & I have been having unprotected sex. However, we have had unprotected sex in the past and, using the pull out method, I have not gotten pregnant. Although I know this does not always work. Am I pregnant? If not, what else could be wrong?
