Hi … So My Last Period Was In May Round About The 13-16 May … I Had Unprotected Sex The Day After My Period Ended… And When It Came To June, I Skipped My Period, Which Never Happened To Me Before … Im Now Two Weeks Late, Did A Pregnancy Test But It Came Out Negative … Did Anyone Else Ever Experience This Before Too? I'm Not Sure If I Should Take Another Test In The Next Week Or Two? Or Do A Blood Test … I Don't Feel Any Different Besides My Boobs Being Abit Sore Sometimes And Massive Headaches …

It is possible not to have a correct tests two week after missed period.

Also, did you take the test, first thing in the morning as soon as you woke up with first urine of the day? Do that for best results.

Stress, change in life style and other issues can cause a period to be late.
Test again, first thing in the morning, if you did not. If negative wait one week and try again.

Maybe book an appointment with your doctor about this. Everything lines up with you being pregnant. Make sure if you take a home pregnancy test to use the first urine of the morning and maybe done one in a week or so.
