I need advice
My period is 8 days late. But on the 3rd day late, I got a negative test. My periods are typically very very regular. I have been extremely stressed. My breasts aren't sore. I'm nauseous but, I'm taking a medication that nausea happens to be a side effect. I'm having headaches but I haven't been having coffee everyday so I'm thinking it could be that. What should I do?
