Hi, I am on day 22 of my cycle, I ovulated on day 14 or 15, not sure, I had some pink tinge in my discharge a few days ago, every day I'm having some cramping! For the last 3 days I have had headaches and been nauseous, I have 28 day cycles. And I am using the bathroom constantly, even if I only go a little bit(TMI) I still go quite frequently. My boyfriend and I have been ttc for8 mo. Could I be pregnant?
