My cycles usually run on average around 32-35 days. My last AF was September 27-30. My husband and I have had unprotected sex several times. I'm now about 15 days late with no signs of AF. I have taken 3 HPT but all bfn. Only symptoms are tender breats and bloating with a slight increase in weight (3lbs). I want to wait a couple more weeks before seeing my doctor but it's hard to believe that you're not. Anyone experience a + after many - tests? Could I be pregnant??
