Hey, I had unprotected sex sept 15th and 16th and the 21st. He finished inside me each time. I'm almost 23. The last couple days my breasts feel so sore like they are bruised near armpit. Thursday my nipples are so tender and still are. I have never had this before but when I went off the depo shot a year ago my boobs got this sore but they slowly tapered off and now they hurt again. Why? My period was sept 7th so should have came yesterday. I am regular and get my period every 28 days. Wednesday night I had really bad cramps and had to take an advil which is weird I get cramps so early with no period. Usually when I get cramps it means my period is here. Since then I have just had very mild cramps mostly when I am laying down otherwise nothing. I'm not with the guy anymore so I am really scared. I feel like my period might come but nothing.

Sometimes women have periods that are late. It is normal. If your period is more than two weeks late, take a test.

I agree, some periods are just late, and you will need to wait at least 10 days, and 2 week is better and then test using the first urine of the day when you wake up
