I was supposed to get my periods on 22nd nov. I had unprotected sex on 23rd nov but my partner didn't ejaculate inside me.
I took a test on 30th nov and it turned out to be negative. I still haven't got my periods yet. Please help.

Can please anyone answer.

Yes, if you had sex on 22 of Nov, it will be most likely 22 to 30 of Dec before you can take a test, No test will know a week after sex if you are pregnant.

So you wait and wait till next month and see if you get that period, if you don't get that period, wait 10 days after missing it, and do a pregnancy test. Always do it with first urine of the morning.

Does not matter if he "finished" inside you or not, plenty of sperm in early fluids.

But since I was expecting my periods on 22nd Nov and we had sex on 23rd Nov, doesn't it mean that I was in my safe period.
