False labor :(

Hey all I will be 39 weeks tomorrow, due Oct 22nd. Still working full time as a medical assistant and have been completely miserable.. the pain and pressure I’ve been having makes my job difficult. So today I went to work as usual, was fine until about 10:00 am I started having contractions.. timing them they were 10 mins apart. They continued to stay at 10 mins but became back contractions until noon. Then switched to 7 mins apart for an hour, and 6 mins around 1:00. My coworkers encouraged me to leave because things seemed to be progressing. I was hesitant but after texting my fiancé he agreed. So I went home, in the car they were 4 mins apart! Talked to my doctor and they alerted the hospital we would probably be heading there soon. My fiancé met me at home, got me in the shower... and when I came out of the shower everything seemed to stop. I got extremely tired and laid down and slept for a few hours. And no more contractions. Just some back pain and general all over body pain. Lot of pressure in my pelvis. This is the second time I had this happen this pregnancy and I’m at a loss! My contractions get worse, are timeable and very regular, but then it all stops. I am exhausted. I was wondering if anyone else has been having this happen to them or any advice or nice words for me haha because I need to go back to work tomorrow like NOPE! FALSE ALARM. I’m over this pregnancy - I just want to stay in bed and cry until she comes out.
