When my wife and I decided to try for a baby and stopped using protection, the very first pregnancy test she ever took was positive, and we weren't sure we were reading it right because we'd never done this before. Unfortunately she miscarried pretty much immediately (fetus never developed a heartbeat). We tried again, but had no luck for several years and eventually made an appointment with a fertility clinic. Literally the very next day she tested positive, and we now have two kids.
