My last period was August 7-12 maybe the 13th. I had sex on the 17th-20th, unprotected, we did the "pull out method". My periods are regular. I'm now 9 days late tho. I took a test the fourth day I was late and it was negative, and then I took one the next day and it was negative. I'm having really bad headaches, and cramping like I'm about to start, but nothing comes. I've been urinating more than I usually do. I also have been extremely tired. There's white creamy discharge. I am always nauseous, and I threw up once. I get dizzy in the mornings also. Could I be pregnant? And when should I test again?
Wait another few days and take the test again. Some women do not produce high enough rates of preg hormones to be detected early in pregnancy. Women with very regular cycles can experience changes in their cycle, even missed periods for variety of different reasons. If you miss another period and the test is still neg, check with your physician who can perform blood test.
