7weeks late Poll

I haven't had my cycle since oct.4,2009 I have regular cycles so I tested with two separate hpt both came back negative..anyone else had a pregnancy not show until later on? I've scheduled a appointment with my obgyn..

• wait a week & retest
• go directly to obgyn for blood work
• it's possible pregnancy wasn't confimed til week12
• could be a start of irregular cycles
