❓False labor❓

So when I woke up this morning I immediately had some pelvic pressure & what felt like period cramps but very low like in the cervix area. I stayed in bed a little while longer than I normally do after waking to see if it would go away on its own. It did eventually after about 45 minutes. So I got out of bed, got dressed, ate breakfast & started sweeping the hallway & living room like I normally do. Sweeping had to be cut short because I got more pelvic pressure & the top of my tummy got super tight & it wrapped around my sides into my back. I sat down, drank some water & they eased up after about 20-30 minutes. Later that day I went to Walmart with my fiancé. We were only in there long enough to get a few scanes of yarn for a baby blanket I’m making & to get a thank you card. Walking back to the car the tightening & pelvic pressure came back. By the time we had gotten home (literally less than 3 minutes) they were still there but very dull. The rest of the evening they kept coming back in bursts but weren’t regular. After supper I was working on the baby blanket & the tightenings hit me like a ton of bricks. I can’t breathe because it’s so tight & I start hyperventilating to catch my breath but I can’t. My face gets all tingly, & the pelvic pressure is insane at this point. I call my sister (she’s had 4 kids) & she comes straight over. She helps me time the tightenings & helps me try to walk through them. They were lasting between 30-50 seconds & between 1:30-3 minutes apart but they weren’t consistent. I’d have a 40 second tightening & would get another one 1 minute & 10 seconds later that lasted for 30 seconds & wouldn’t have another for 2 minutes & then have a 50 second one 1 minute later. We kept an eye on them & they eventually eased up after about an hour & a half. I was exhausted at that point so I went straight to bed. It’s now 3am & I’m starting to get tightening again but they don’t take my breath away like earlier this evening. The pelvic pressure is still there & the period cramps are back.

Is this real labor starting or just some crazy false labor? I’m 34 weeks (FTM).
