I am 8 days late on my period... THis weekend is going to be 2 weeks that I had sex with my boyfriend... I have done 4 home pregnancy test and they come negative.. What should I do??

It may still be too early to test. Wait another week. If still no period, take another test. Make sure you use first morning urine.

There are other causes for missed and late periods. Change in eating habits, exercise, stress. Just to name a few. You also didn't mention anything about birth control. Starting, changing, or stopping birth control can cause a change in your cycle.

Thank you... yes I am going to wait another week... I haven't changed my eating habits or haven't exercise nothing like that... I stopped birth control in July... For three months straight my cycle was normal is just that this month I haven't gotten my period and don't feel like I'm going to get it...

Then, and I'm assuming you've had sex, it's certainly possibly you're pregnant.

Have you been stressed at all?

No I haven't I had sex just that last time... I have not been stressed at all...
