-- Posted by coughcough at 11:04 am on Dec. 27, 2008 ok this is solved and can be locked now -- Posted by major at 11:04 am on Dec. 27, 2008 the day of your missed period -- Posted by JennyColada at 11:05 am on Dec. 27, 2008 It depends, but I think most women probably figure it out in about a month, when they miss a period. I'm sure there are statistics on it, but I'm too lazy to search. -- Posted by Just Waiting Here at 11:05 am on Dec. 27, 2008 How soon?  Some pregnancy tests say they can do it about 5 days before your period is due.  However, many women can't get accurate readings at this time.  In general, to make sure you get a good test reading, if you wait a few days after your missed period, you can get a much better result. -- Posted by psychoticboy at 11:05 am on Dec. 27, 2008 im on the same boat you probably are -- Posted by samantha89 at 11:06 am on Dec. 27, 2008 with a sensitive test about 5 days before your missed period, but for best results wait until the day after you miss your period. -- Posted by AprilAnn at 11:22 am on Dec. 27, 2008 the whole period thing isn't technically correct. for some girls, they can still be pregnant and have their period. my best friends mom didn't know that she was prego until she started showing. because she had her period the whole time. so just go and take a test. take a few of them until around the time you think you might have had your period. and if it says positive, then you know. -- Posted by major at 11:31 am on Dec. 27, 2008 Quote: from aprilann at 11:22 am on Dec. 27, 2008 the whole period thing isn't technically correct. for some girls, they can still be pregnant and have their period. my best friends mom didn't know that she was prego until she started showing. because she had her period the whole time. so just go and take a test. take a few of them until around the time you think you might have had your period. and if it says positive, then you know. stop spewing bullshit, it's physically impossible for a woman to have a regular, normal period and to be pregnant, because it SHEDS the WALL of the UTERUS, and if there was a fetus in there then it would be expelled too -- Posted by islandgirl at 9:04 pm on Dec. 27, 2008 Quote: from Major at 11:31 am on Dec. 27, 2008 Quote: from aprilann at 11:22 am on Dec. 27, 2008 the whole period thing isn't technically correct.    for some girls, they can still be pregnant and have their period.    my best friends mom didn't know that she was prego until she started showing. because she had her period the whole time.    so just go and take a test. take a few of them until around the time you think you might have had your period.    and if it says positive, then you know. stop spewing bullshit, it's physically impossible for a woman to have a regular, normal period and to be pregnant, because it SHEDS the WALL of the UTERUS, and if there was a fetus in there then it would be expelled too This is true. I have to say though, you can have bleeding that may be wrongly interpreted as a period during pregnancy- bleeding for other reasons. It's generally a lot lighter and I think most people would notice the difference. I don't think that has anything to do with the OP's question though. -- Posted by babybluebitch at 10:40 am on Dec. 29, 2008 by taking a thing calleed A PREGNANCY TEST duh how dumb can little kids be dont have sex unless your smart about  buying a damn test -- Posted by angel2fire at 4:53 pm on Dec. 30, 2008 I knew within 3 weeks because of the way I felt emotionally, bloating and feeling sick. A test confirmed it a few months later. Many women claim to just know, but only a test can tell if you truly are. -- Posted by Points at 6:32 am on Dec. 31, 2008 Look at this. -- Posted by stinaaa at 10:41 am on Dec. 31, 2008 some people just dont even know. for example: i know a girl who didn't know she was pregnant until 3 months in to it. She ended up in the hospital for pains in her jaw- and they told her she was pregnant. Biggest shock of her life.
