I've been having unprotected sex for almost 3 months now and my period is irregular so from what I hear is that it's hard for me to get pregnant with an irregular period. Lately I've been feeling weird as in my boobs hurt so much, I've been so emotional and I'm always out of breath when I go up the stairs or when I do a lot of movement. I'm not sure if I'm about to start my period or that I'm pregnant. I took a pregnancy test and the line is very faint. So what do you girls think ? Am I pregnant or not ?
