If your periods are always iregular normally when should you take a pregnancy test because it says to talk it after your missed period but you never have a regular period so you don't know if its late?
just wait to see if it comes in a few days if not take a home pregnancy test.if possitive see your docter.
If you have regular periods and you are a week late you take a pregnancy test and it was negative what could it be?
I had Implantation 11 days after my period when my periods were irregular then next month they went regular for 3 months now its the 4th month and I'm 1 day late?
It is not likely. Although the periods, really don't matter. It is the ovulation that is necessary for pregnancy. But it is not likely that you are ovulating if you are not having periods. You should consult your doctor for reasons of not having a period and you can discuss your pregnancy options there.
up to four days to your expected period though at that time it is generally not as accurate i would talk to some one in a pharmacy to recomend a test to you, from what i know first response is pretty accurate, if you have iregular periods i would wait until about ten days to two weeks after possible conception to take a test than that way i twill be a bit more accurate
