I'm a bit confused ATM...

DP and I did the deed, unprotected the day before AF was due.

AF was due yesterday.

The night of the deed and morning that AF was due I was so sure I was getting AF, I had cramps which felt like my normal pains.
The morning AF was due, I went to the bathroom when I got up and (TMI!!!) when I wiped a very very light pinkish discharge came out. I thought it was the coming on of AF, but it has now been almost 2 days later and nothing... even the cramps and pains have gone?!

This was the only time we had unprotected sex this month... and usually AF is a few days early, never really late.

Considering AF is 2 days late can I take a HPT? Or will the results be inconclusive due to the fact that we only had unprotected sex 2-3 days ago?

*Some extra info on the month is* I have been stressed out a lot more than usual, so this could be a major factor of AF being late. I would just put it down to stress IF I didn't have unprotected sex and ontop of that the light pinkish discharge yesterday morning.


Racking my brain here!!!

TIA for any info/advice.
