first trimester

Niana

anyone had slight nagging cramping in the first trimester I'm 6 weeks 4 days pregnant had an ultrasound done at 6 weeks 1 day and saw a little heart beat now I've seen that I'm petrified I'm going to miscarry so I'm up and down to the toilet every half hour to check , I've been having cramps for about 2 weeks but I've had no bleeding and there not really painful there just nagging cramps any other ladies had this
