I am currently 6 days before I'm suppose to start my period. Lately I have been feeling nothing but heartburn, dizziness, and the feeling that I have to vomit in my throat. My boobs are very tender. Lower abdominal pains and weird feelings in my stomach. I've had intercourse on three days of my ovulation(unprotected) and on the very last day of ovulation where you're most fertile(unprotected)...and two-three days after that(unprotected). Maybe I'm taking test too early? I'm using the cheap $.88 ones. Could that be an issue? I'm getting negative results but positive symptoms. I've had intercourse for more than 10 days unprotected since the 6th of April. Is there a change that I could be pregnant? My partner has always used the pull out method. He has never 'finished' in me. Could you get pregnant from precum?
