When should I take a pregnancy test if I have a late period?

My period is late this month, and I'm afraid that I may be pregnant. The weird thing is, though, my partner and I never actually had actual sexual intercourse (in other words, there was no penetration). I'm wondering if the wet environment could still be a risk. I'm hoping that it's due to stress and fatigue with finals coming on that causing this delay. How long should I wait before getting tested?


Am I anorexic if I can never decide what to eat?

I have a problem with food. I hate it and never know what I want to eat. Sometimes I'll be famished to the point of shaking, and I'll just lie there thinking about what to put into my body, sometimes for hours. I know I should eat something, and I really am hungry, but at the same time, nothing appeals to me. Is this a form of anorexia? Or could it be a symptom of stress, depression, etc.? I would really appreciate it if you could help me.


Do I have bulimia and will it interfere with my birth control pills?

Once a day, after meals — whenever my roommate isn't around, I stick my fingers down my throat and throw up most of the food that I had just eaten. I do not binge — I only purge. I understand from my Psychology professor that the diagnosis of bulimia nervosa requires that the person binge and then purge. I am curious, then, what I have — do I have a form of anorexia nervosa or what? Also, I am on birth control pills and I am afraid that I might hurt their effect by throwing up. How long does it take for the pill to get absorbed into my system? I usually don't throw up until about 5 or six hours after I have taken the pill. Will this hurt the effect of the pill?
