A little back story. My period used to be really irregular when I was younger. When I went to a doctor I was told I had ovarian cysts and prescribed birth control. After the cysts cleared I stopped the birth control and my period has been relatively normal since then, with a few days early or late every now and then.

Forward to now, my period is now 19 days late. Every pregnancy test I’ve taken so far has been negative, including the one I took today. Not even a faint line. But for the past week and a half I’ve been feeling crampy and tired, even though I get plenty of sleep at night. I was at the doctors for a checkup about a week before my period was due and he said everything was fine and there were no cysts. So I guess my question is, could I still be pregnant even if all tests are negative?
