Well the women I have known have had normal flow at the normal time monthly so wether it is considered AF or not you be the judge.
I wouldn't say it is common or that it happens often.
As Christie and Hthr said, it is not possible for it to be a "period".
A menstrual cycle is the shedding of the lining of the uterus. Over the course of the month, your uterus build up a lining getting ready to "house" a baby for nine months. The zygote implants in this lining. If you have a "period", you are shedding this lining, and essentially the unfertilized egg with it. When you miscarry, you are shedding the lining and the product of conception.
It is possible to bleed while pregnant, but no not common and definitly NOT normal. Any bleeding should be brought the attention of your care provider.
I have a friend who bled like a period her first and second month of pregnancy. The doctor did an ultrasound and told her that her baby's heart stopped beating and she was miscarrying. The doctor told my friend that since she was already miscarrying, he wouldn't do a D&C. Well, thank God she didn't. That baby is now 3 yrs. old. Also, go to this web-site to read an incredible case of a woman who bled in her pregnancy. It is something. http://www.epinions.com/content_3524173956
Okay listen i dont mean to sound rude or anything but whats with all these women saying they have had friends that have had normal periods during thier pregnancy? Do you have any idea what a period is? its the shedding of the inner wall of your uterus. if u were pregnant than the baby would not be able to survive this. my only problem with these women saying they had normal periods while pregnant is that they are mistaking a "period" with implantation bleeding or other forms of bleeding. when u post comments on this website and say that u have had friends or u yourself have had periods while pregnant people read this and become confused. not all women reading these comments want to be pregnant. some women are tring to find out possibilities that they are not pregnant. i know it doesnt seem like a big deal to call any form of bleeding a "period" but when a "period" is the last clue to tell you your not pregnant, than all of a sudden we can take off the " "
on period and start understanding that a period is a lot different from just any "bleeding."
thank you for reading this comment and by all means if anyone can prove that a period is possible while being pragnant scientificly and medically i will be happy to repost another comment stating my lack of knowlege and ignorance to this matter....
thank u for your time.
Ya i'm one of those ppl that hoping i'm not pregnant. My period seems to be around 6 days late. i have the cramps and everything but i'm still very worried that i am. if i am i should be 3 or 2 weeks pregnant since my research found that the ovary comes out 14 days before your period. I'm totally lost and confused since i did get my period.
I think that periods during pregnancy can happen. I think that it shouldn't be said that it's not normal, but a rare case. It may not happen often, but we learn new things about the human body on a regular day to day basis. Like when a woman truly believes that she's pregnant, to the gaining weight, all the way to the lactating of the breasts, but the woman later on finds out that she was never pregnant to begin with. The uman body has been own to do many wonderous and undocumented things. Yes, it should be reported to the OB/GYN. To be on the safe side everything should be reported to the right doctors. ANything is possible in these years and many more to come. I feel that we're gonna hear more rare experiences in the future. It's just that others don't want to talk about it all that much because they feel it's out of the ordinary and they sometimes get told that it never happens. Like I said before, when it comes to the human body, anything is possible.
