Hello! I have spotting for 38 days now and yesterday it started getting pink. This morning it's still pink when I walk around a little bit. ? Is this because my cervix is starting to open? It's also starting to hurt in my lower back like during my period. In my first pregnancy everything was different. Do you think I should go to the hospital? Thanks for your answers.
