I had sex on the 10th and the 12th of this month and my period is due around the 28th.

I started having slight cramping on the 18th which is unusual for me because I hardly ever cramp with AF.

Since then I have been waking up with night sweats, frequently needing to urinate, heartburn (which Ive never ever had), extreme gas, bloating, headaches and a weird stabbing pain in my belly button.

Also I know it may sound crazy but I just feel pregnant, its like I just know I am but I keep getting negative early response tests so its very discouraging.

I have never been pregnant before and I am 21 years old and very healthy so I dont know why else I would be having all these crazy symptoms, could the tests just be wrong?
