Contractions at 14 weeks?

Just came back from my 14 week doctor appointment and after she did a mini ultrasound, she said everything was alright with baby. However, when I mentioned that yesterday I had some abdominal pain, very similar to period pain, she said those where contractions, not the braxton hicks kind, but real contractions and that it was not good. She recomended that I increase my water intake and to rest more.

Now, from what I read on this app and other sources, I thought some degree of abdominal pain was normal in pregnancy, as long as there was no bleeding or anything....

I am already working half time and not doing exercise, I don't know how much more rest I can get...
