So like can cervix checks start labor?? I know that's probably a stupid question but like I got a check this morning and I was 2cm dilated and almost completely thinned. And they said I might spot a little after but like after the check I started getting period cramps and then about an hour later I had blood mixed with discharge. It was a lot more than just some spotting. And now I'm going between pains in my back and period cramps..
