hunni, it sounds like you haven't got pregnant yet.

it sounds like your period isn't 28 days apart at all but more like 30-32 days.

from your post it does sound like you aren't too clued up on pregnancy, so maybe you should get some books from the library and bring yourself up to speed on stuff.

You can ask questions in here too, there's usually someone around to help.

the cervix is the opening to your uterus, the cervix doesn't have a wall.

you're going to need to be having sex at the right time as well. - typically mid cycle for most women.

You might want to get a general health check from your doctor as well, because typically people fall pregnant within a year of actively trying, but then you could have been missing your fertile times. A health check is good and also start taking pre-natal vitamins and make sure your diet is healthy and balanced.

Oh, I know things about pregnancy and stuff ... My boyfriend and I have been trying for quite some time. I have always been on a 28 cycle, but for a few months I've been late all the time.

This past month I was to be due March 14 but didnt get my period til March 20 ... every month it becomes later and later.

I just want to know what is going on and why my period is always late.

you need to see an ob/gyn hun
