I have a feeling I may be pregnant . I'm not sure how soon I am able to tell or take a pregnancy test because my periods are very irregular. The last period I had ended on July 5th, and I had sex on July 7th and 9th. It was unprotected, he pulled out, I do realize that is not always effective. A lot of times my periods come every other month and last about a week, so realistically, I'm not expecting a period again until early September. The past week or so I have felt extremely tired. I have not had any sort of morning sickness, however, I have had moments the past couple days where I have felt a bit queezy. If I take a home pregnancy test within the next couple days, how accurate will my results be, although I am not expecting a period? Thanks for your time.
