Question!

I’m 20 weeks and some days. Ive been having some dull cramps in my lower stomach and kinda on my side towards my back. Is this anything to worry about? She is already head down and low so they are watching me. I wasn’t dilated when I they checked me. (I had been having Braxton Hicks so he decided it was best to check) should I go in to the er or wait it out until in the morning and try to see my doc then? I don’t want to “dramatize” this. I just want everything to be okay! Thanks in advance!
