Should I test again?

[tiffonews]

So I had sex about 3 weeks ago (my first time; twice in one night) and it was unprotected BUT both times he pulled out. I have not had sex since. I took two Waitirose own tests the first day I was late for my period (Thursday), which were both clearly negative. But now it's the fourth day since I was supposed to come on (its Sunday) and I'm still late. I don't think I have any symptoms. Sorry for the TMI, but my nipples look a bit larger than usual, and I've been feeling sick a lot, but the nausea is not unusual anyway. How long should I wait for my period to come before I try testing again? Should I get a a Clear Blue one?

Thanks x

I would get a clear blue one, despite what some people say they've always been very accurate for me and I found out I was pregnant using the clear blue digital 3 days before my period was due. Just make sure u pee in a pot and dip it for 15-20 seconds as I think it's more accurate.

And that wasn't my morning wee either that was just a dribble cos I didn't have much left!!
