Do you think I’m pregnant?

So I’ve missed 2 periods now but all the tests keep coming up negative. I’m on cycle day 70. I went to the doctors and he said if the tests are negative I’m not pregnant but I’m really irritable lately and my boobs are really sore and my stomach looks like this? Not sure if i can keep blaming it on Christmas dinner and winter fat anymore. Do you think I could still be pregnant even if the tests are negative?
