I have unprotected sex with my boyfriend every night. I only take the birth control[and green pills which do nothing] before we have sex (could be 3am or 5pm or 12pm..)because im always up at really random times and sleep whenever im tired (naps during day sometimes). I believe the last time i had my period was 2.5 weeks ago, but my periods are so random there's no point in keeping track of them. I either get periods within 5-14 days (usually 7-9 days long) and sometimes they have a tendency to clump up, having 2 periods one right after the other, and not having the next one a month or so later..My eating habits, excersize habits and stress levels are always radically different or spontaneously on random schedules, and i get sick or injured alot so its really hard to tell if i ever have symptoms of something related to being pregnant or anything else..I just bought another pregnancy test but its hard to know when to take it, if i dont know when my next period is. I took one a month ago and it was negative, yay. I work and am attending cegep again next semester along with training again. I'd really like to know besides buying these pregnancy tests if im liable for being pregnant, because I alone cannot tell.
