Ladies help!!

I know go to the Dr but I wanted some other opinions. This is my second successful pregnancy and first set of twins. I am 9 weeks. I woke up and got some pretty sharp cramping going on in my groin region. No blood.

I do nothing but walk at work and I worked second shift last night. They feel like period cramps which have always been bad for me... But wasn't sure if it is normal for them to feel this strong. I called off work to rest and hydrate. Working in the hospital I don't get to hydrate like I should.

Thank you!

Please be nice, no rudeness.
