2 weeks late

Col
Hi everyone. I'm two weeks late today, CD 49. My cycle seems to normally be 33-35 days. My doctor did a blood test Wednesday, I got the results today and they were negative and my hormone levels were all good they said. Is it possible I could still be pregnant even with the negative blood test? Or did I maybe just skip a month? I've been mildly crampy on and off all week, but nothing like I would normally get before my period really. Just curious what everyone's thoughts are. If you need more info, feel free to ask. Thanks!
