Does it sound like I maybe getting ready to go into labor?

Hey mamas🩵

So I’m 37w&5d and woke up this morning feeling just icky… I had this sharp pain while laying on my left side and it took a bit of time to get it to subside once I started moving for the day. Baby is as active as he normally is but all day I’ve been feeling a lot of pressure down there with cramps that feel like your period is coming on and lots of Braxton hicks (bh) not every BH had cramps with it though. I drank lots of water and some juice all day. Ate well and rested, haven’t gotten overheated etc but as the evening went on I’ve been getting even more uncomfortable to even lay down, sit or even stand. And in the last hour I’ve been feeling a lot more pressure down there accompanied by BH that are coming a bit more consistently maybe every 15-20 mins. But then again there not accompanied by cramps. I did also have sex a few times today too 🤦🏽‍♀️ but other than that I’ve taken it easy. This is my 5th pregnancy and I’ve just never had this happen. And not sure if it matters but at the doctor yesterday I was also 2cm 70% effaced

What do you guys think it is? And what should I do?

Thanks in advance!

Update: decided to time them so yawl could see. These are also without pain just very tight tightening
