The home tests only show if the hormone they test for is present. They can't ever tell you if you ovulated so I wouldn't worry about getting one now. When I O I get cramps similar to AF cramps (although I never get them anymore, but they are similar to what I used to get). The following day my skin breaks out (even though I'm 40) and I get lower back pain. Not sure if that helps you, but that's my experience.
