Painful contractions!!!

For the past week I’ve had mild contractions mainly in lower back. And yesterday they became SOOOOO intense it put me in tears. Now 24 hours later they are 15-30 minutes apart. I’ve done the warm shower, water, eating, and feet elevation but I’m starting to get worried because I’ve been having a headache that Tylenol, water, and eating aren’t helping as well as back pains on a scale of 1-10 is a 7 and nausea that makes moving unbearable!!!

Any other ladies have these issues? Any resolution to become a little more comfortable? How far after these feelings did baby come because although this is my 3rd pregnancy my body is failing me
