My last period was January 22, and was normal the first day. The other two was light. After my period I had continuous cramping. I started bleeding on the 27, so I was about 5 days late. I feel pressure on my lower belly and can't tuck it in as much. I have been experiencing some of the symptoms, such as; cramping, bloaded, headaches, heartburn, craving, and dizz. Am I pregnant??
