Hello, Well long story short I am 11 days late for my period. My last cycle ended 9/10/12, I was supposed to get it 10/8/12 or around there. I had protected sex with my boyfriend twice before I was expecting my period on 9/19 and 10/1 we used condoms as well and pulled out before it was time for him to ejactulate. I took a pregancy test sometime during the first week and it came back negative, went to the woman's hope clinic and took one and it also came back negative on satuday morning, and two other digital tests and they also came back negative. My boyfriend tells me it may be stress because I started a new job and have exams that I need to pass that I'm worrying too much about causeing me not to ovulate but I don't know what else to do or what can be causeing this.

Wait until your next period is due. If you miss it, test again. Make sure to use first morning urine, or see a doctor for a more accurate blood test.

Some women don't get a reliable test until well into their second trimester. It could just be too early to test, or you're testing incorrectly.
