I really need advice and I hope someone could help. But on April 4th I had sex with out protection. Didn't take the morning after pill, I was suppose to start on April 18th, had sex on Sunday and took Plan B just in case something wrong happened (used protection that time) I bought pregancy test. Took one on that same day and took one on Monday just to be sure. Both said negative and it's been 5 days since missed period should I be worried?? Desperate for advice
