Okay so I haven’t had a period since October 26. I’m 28. Never miss periods like this, I’ve had three kids and tubes tied. I’ve been to the doctor they say urine pregnancy is negative and all my hormone levels are normal, they’ve tested my thyroid pancreas liver kidneys, everything. But still no period. I feel like I’m pregnant but I keep getting negative tests and the dr visits don’t seem to help. Anybody else had this happen?
