Well, if you are habitually using Plan B, it can really mess up your cycles. I would take a HPT, then when you get the results, go to your Dr. for A.) BIRTH CONTROL or B.) If you are pregnant, you need prenatal care.
You do not need to take a pregnancy test on your period. If you are having a period then you're not pregnant. Prenatal bleeding and periods are two different things. Also, and this is MY opinion, I wouldn't take Plan B like that. It's a ton of hormones that mess up your cycle.
I just wanted to add that you can still get your period when you are pregnant. My Mother had full "periods" with all of her pregnancies, She bled for 5-7 days each month.. as did one of my siblings. Having a "period" doesnt necessarily rule out pregnancy. Definitely decreases the chances since most women stop getting a "period" But NOT all women do! =D
You don't get your period while you are pregnant. The actual act of a period is impossible since your not ovulating. However some people get decidual bleeding which happens around the time that your normal period would be due and lasts for as long. Its where you have a build up of hormones and your body remembers shedding the lining of your uterus while have a period and goes on to do the same thing... however there is no egg and no actual cycle and it usually only happens during the first trimester of the pregnancy.
there is no point in taking a pergnancy test on your period. that would mean your not pregnant.
Kim1989~ I'm sorry if I tick you off with this. My mom had period LIKE bleeding while pregnant with each of us for the first few months. she CAN Take a pregnancy test, because the bleeding she is experiencing can possibly be period LIKE bleeding. I'm not saying a period but like one.... it is possible. :)
