Frequent Braxton Hicks

I’ll be 33w on Wednesday with #3 and I feel like my bh contractions are happening very often. I’ve brought the concern up to my doctor and she said to come in to be monitored if they are happening 5 in an hour. Well up until yesterday they were happening just a few times a day with only every so often having big clusters. I’ve felt completely off and and exhausted so I’ve been trying to keep track of them. They were happening every 30min to an hour last night or less. I was actually able to sleep without having any last night ( the night before I had 3 during the night that woke me up) well since I’ve been up this morning I’ve had one every hour almost to the minute and I feel like I have kind of burning cramps low in my abdomen in between but no tightness. I know what real contractions feel like but I’ve also had very inconsistent labors with my last 2 and my last I had inconsistent contractions starting at 36weeks and that is what my doctor thinks caused my placental abruption at 38w. I’m trying to take it easy and drinking plenty of water but it’s not changing anything. Anyone have the same problem?
