Hey Bec,
I have experienced a similar thing. I started off with really bad cramps, then they eased off, so now they come and go. I had a couple of days this week where nausea disappeared and cramping eased entirely, but instead of feeling relief, I felt worried! LOL, it is such a roller coaster isn't it? I am sure the cramps will be back, as mine come and go, and I am sure you will see a lovely little heart beat on the ultrasound,

I know it is hard not to worry, but try not to as it seems normal to me,

*hugs*
