Can someone help me suss this out?

[Alicia870]

My period is late. Should have been here well over a week ago.
I had unprotected sex 2 days after my last period ended(this was over a month ago now). I know unlikely to cause pregnancy but still possible. I did a test 2 days ago and it was negative.
Question is should I test again or because I had sex over a month ago is there no point testing again? Just wondering where
my period is!!

I think if you were pregnant and a week late you'd get a clearly positive result. I don't think you're pregnant, are you stressed, eating enough etc ?

You aren't pregnant (if that was your last time having sex protected or unprotected). At the very outside, you'd get a positive by 20 days after sex.

You ovulated late which will delay your period by the same number of days.

Thanks ladies - that's what I thought but just wanted confirmation!
Can I just ask for future reference (as I will be ttc baby number 2 in a few months time), say for example I fell pregnant during this cycle and period is a lot later than usual, possibly weeks, how would the dating of a pregnancy be? I know they take the first day of your last period, but as I've ovulated so late, surely that due date would be massively inaccurate??

Dating is taken to be last monthly period until the 12 week scan, when due date is altered. If it's way off, they may have you come back for a re-scan.
