False labour

So this is my second baby. I have been having braxton hicks since 24 weeks. Yesterday afternoon while resting I noticed I'm having some cramps that seems to come at regular intervals. I started timing them and realised they were coming every 5 minutes, lasting about 30 sec. I lay down but it continued for about 2 hours. Then came back again on the evening for about an hour - same cramps regularly and lower back pain. And I'm currently having them again, assuming it is false labour as I am only 34 weeks tomorrow. Anyone else going through the same? Do I just keep resting and keep an eye on them, do I ring the hospital? 🙈
