So I have been having contractions while at work, they aren't like horribly pain full but deff bother me. I'm 28 almost 29 weeks and it only happens when I'm at work. I do stand all day while at work. Should I get this checked or even go to er to be safe? It's been happening for the last three days now. Opinions please!Β
