I have been experiencing signs of pregnancy for the past week or so. i have taken a couple different test and one came back positive and two where negative... the one that was positive had a very faint second line but i could still see it with no problem, i have also been feeling nauseated, fatigue, and increase in appetite and cravings like for pickles. the sperm how ever looked like it only got on my boyfriends pubic hair, is it possible some got inside without us noticing and is it likely that im pregnant? oh i havnt had my period for about 2 or more weeks
