So confused, please help... early labor/false labor

Last night around 11pm I started having "contractions". At first they were 15, 20+ min apart. After midnight or so they started to get between 6-8 min apart, lasting about a min and half. I had period like cramping and tightening with every one and it would take my breath away a little. I also had backache with them along with pressure in my pelvic and butt. And losing pieces of my plug- not alot. I had drink about 3 glasses of water when it first started and layed on my left side just in case it was intense b/h but that didnt help, even tho my b/h have never felt like that. Also I had bath before they started.

This went on until about 8am this morning when they suddenly tapered off? So I decided to finally rest, slept on and off til about 1pm. Got up felt like i needed to go #2, nothing happened tho. Had a few more inconsistent contractions that weren't as strong or long. I'm still getting some, 15 min apart, 30 min apart sometimes even an hour. Some are very strong like last night, others are not. It seems like they are trying to "build" back up and are starting to get strong again, but I just dont know.

What is going on? Is this just false labor? Its been very exhausting and now stressing. 😕
