Bad abdominal cramping 😖

Jessica • 23 year old Health and Safety Officer TTC#1
Okay mummas, please help!? 
I am currently about 6 weeks with my first.. And for the last 2 weeks I have had really uncomfortable abdominal cramping..
It's almost like I'm in the middle of a really heavy AF. It's not a sharp pain, it's rarely one sided and I've had no spotting.. BUT the cramping is really starting to bother me. 
I'm sitting at work, and I feel like I'm being kicked from the inside... Today.. It is bad ! Is making me feel sick ! 
Is this normal?? What can you do to ease it ?
I want to curl up in a ball right now and cry, I'm really struggling with it..
Please help!?
