I missed a pill a couple of weeks ago. I took it the next morning when I realized. My husband and I haven’t been trying for a baby but we’re not being careful either. For the past two weeks I have been feeling nauseous and I’ve had a lot of headaches. I’m also a teacher so that could be why but still lol. Today, I’ve had some breast tenderness. I took a test at the beginning of last week and it was negative. Is it possible to have symptoms before the test can tell? Any help is appreciated. Thank you!!
