When shall I test?

[whyIsARavenLikeAWritingDesk]

I know it's super super early but I just feel different.
My DP DTD on Thursday just gone and I was due my period over the weekend but still not arrived.
We already have 20month old DD and as much I've entertained the idea of another DP has point blank said no! I am on contraception before anyone says anything.
I had some pink when I wiped yesterday too and thinking this could be a sign??

What contraception are you on? If it's a pull, have you missed any ? It's unlikely you're pregnant if you're on contraception and taking it properly but it does happen. If you're late ,test

Also if your period was due only a few days after you had sex , it's unlikely you'd have been in your fertile period so probably not conceived on that day if you did

You only had sex a week ago which was 2-3 days before your period was due? If that’s the only time you’ve had sex this cycle then it’s highly unlikely that you will be pregnant.

Your period could be late for many reasons which aren’t pregnancy related.
