I don't normally get my period every 28 days. I keep having dreams that I need to take a pregnancy test, which i never have. We had protected sex however, i am not on birth control due to ovarian cysts. My choice, not determined by my gyno. I just would like to know how soon I can take a home pregnancy test without it being a waste, as it may be too early to determine if i am prego or not. Thanks for your help!
