I have missed normal date,periods were due on 03 -07-2013,but still no.
A week before due date white secretion oozes out for a couple of days.
Now vomiting ,nausea in the morning.today is 24-07,
I think the stripe used for home pregnancy was not of good standard, I checked on 31-06-2013 by home pregnant kit...

Take another home pregnancy test and be sure to use first morning urine.

Sort of sounds pregnant to me, why no tests since then ?

But yes, test again, as instructed

Please tell me for how long should I keep the stripe inside urine below the marked sign?
Because the instruction provided on stripe just tell to wait for five minutes outside urine.

Then you wait for 5 minutes. Follow the directions carefully.

Another question is that when I am having sex,I can't feel my husbnd s penis inside me.althoough he has cosiderable length and width,

What are precautions to have sex during pregnancy

There are no precautions during pregnancy unless your doctor has advised you to refrain from sex.
