I really wanna have Case by the end of March. I'm scared to be working past 37 weeks where I work but my bf insist I work as long as I can and honestly I understand but it pisses me off at the same time...it was easy with my daughter I had sex and went into early labor...I kinda feel bad for feeling this way but also feel like I need to protect us both.
