Help?

Nicole
Well I haven't had a period for 3 months. Everything is fine though I've had blood work done and everything. All pregnancy tests are negative blood and urine but I feel pregnant. My belly is growing, I'm nauseous and fatigued and have cravings like crazy. When I press down on my lower tummy I feel what could possibly be my uterus. And it can't be in my head because I tell myself to start my period everyday (I'm not ready) I looked into cryptic pregnancy. I was wondering if anyone has gone through this or been in my position?
