I'm getting annoyed!

Please give me input? I've been testing like crazy so can I literally go from one day a negative to one z positive? Yesterday it was a negative. If anyone has seen my previous posts you'll see that I was on seasonique for three months went off and now odk if it's in my mind or pms but I'm dying to know. I haven't been lTe yet and been stupidly testing too early. Please let me know if I should or can test now or show wait !!! Thank you for the support and advice
