Real contractions or fake ones ?

I’ve been having contractions all morning I assumed they were just BH as they were irregular and just tightenings, got up made breakfast and went back to bed to relax then about mins to 11 they were coming a bit closer I still wasn’t studying them then at 11:26am one hit me and I’m like well that’s a bit more than the normal BH, they aren’t that painful but definitely a bit more intense and my lower back is also now hurting, so since 11:26 I’ve been having them 4-6mins. Also I’m 39+2! But I’ve been having irregular BH for about 2 weeks now. No other signs of labor so I’m just wondering what’s going 😩
