Im about 14 days late for my period. Intercourse occurred the 28th with protection. He even pulled out before ejaculating and from what we saw, there were no leaks when he ejacualted. The only feeling I have now is tender breasts. I'm stressed out and I've heard it all about taking a test is the way to find out. I want to know opinions. Is it my stress holding me back? What is the solution?

The only way to tell, is to take a test. So take a test.

Pulling out does not stop the early fuilds, and often a leak can not be easily seen.
Condoms have about a 3 to 18 percent failure rate.

How regular is your period? Is being two weeks normal or out of the ordinary?

There could be many reasons for a late/missed period but pregnancy is the top one. Tomorrow morning you should take a home pregnancy test using the first urine of the day. To get an accurate result.

If my calculations are correct you had intercourse right before your period was supposed to start?

Do you mean is stress delaying onset of your period, or is stress holding you back from doing a test?
Assuming the former, it's one of too many possibilities to answer.
There is NO such thing as regular as soon as it isn't anymore. 'Usual' means NOTHING. SYMPTOMS like tender breasts can be ANYTHING. NO ONE can tell you whether or not you are pregnant early on. ONLY a test can.
