Hello, I'm trying to get pregnant on my first try. My last periods were January 14th , they last for 4 days and my last one was February 12th, it lasted for 4 days. Me and my partner had sex March 6th when he ejaculated inside of me. Also on March 7th he ejaculated inside of me. What are my possibilities of being pregnant? I don't want to go and waste my money pregnancy test and they come out negative like times before.
